If I'm not mistaken, I did something similar to this piece, but the one before is more like an introduction to the sport of rugby football, from its rather accidental conception to perhaps one of the most popular sports in the world. However, for those who only know rugby on the surface, there are actually two versions of this game. Two versions born out of both rebellious attitude and necessity, despite derived from the same Rugby School kid named William Webb Ellis, who ran with the ball in hand, instead of kicking it.
In the previous piece, I wrote perhaps a detailed description on how rugby football first codified, up until some clubs, mostly Northern England-based, left the Rugby Football Union, formed Rugby Football League, and codified the laws of rugby league as a more professional-oriented game opposite to a more amateur-based rugby union, until both sports became professional only after World Rugby (International Rugby Football Board at the time) declared rugby union open for professionalism in the wake of the 1995 Rugby World Cup, hosted and won by South Africa. And with that in mind, there are some changes that needed to be made to ensure that the fans are treated with an amazing spectacle of hard-hitting rugby, with of course, emphasizing sportsmanship.
Despite the differences, which will be elaborated later on, there are still some similarities between the two codes. They are played using an oval-shaped ball, with a game of both rugby union and league lasts for 80 minutes. The goal is to score more points than the opposite team through four scoring methods. Those methods are a try, which is the act of grounding the ball inside the opponent's in-goal area, resulting in a conversion kick to convert the try, the penalty goal which came from an infringement, and a drop goal, which is the method of kicking immediately after the ball has touched the ground. The ball itself can be advanced by the means of kicking, running, set pieces, and passing. What makes rugby unique from other sport is that the ball can be kicked forwards but must be passed sideways or backwards. The players may tackle one another, but only towards the player who has possession of the ball.
The first major difference between rugby union and rugby league is the number of players in the team. As we all know, rugby union team fields 15 players, while rugby league allows 13 men, which is two less players. The positions are more or less the same, with forwards and backs. But here is the main difference: they use different numbering scheme, and one position in rugby union is non-existent in rugby league. Let's start with the forwards, which are the group of players forming the pack for the scrum, and generally doing most of the dirty work on the field. In union, there are 8 players, while league only has 6. The front rows are more or less the same, consisting of two props (loosehead and tight head) and a hooker in the middle. In union, these three are typically the strongest and the heaviest players in the field, acting as the battering ram of the scrum but with limited ball handling skills. In league, these three instead have bigger physique, with more emphasis on ball control and straight running ability. In union, the props wear the numbers 1 for loosehead and 3 for tight head, with the hooker taking the number 2 shirt. In league, those three wears the number 8, 10 and 9 respectively. Second Row forwards, often called locks, forms the scrum behind the front rows. In rugby union, these two are typically the tallest players in the team, as they might be the prime target for line outs. In rugby league however, since there are no line outs, locks are often a lot mobile with speed and offloading abilities. The locks wear the number 4 and 5 in union, and 11 and 12 in league. The back row forwards are the main reason why there are fewer players in rugby league. In union, the back row consists of two flankers (blindside and openside) and a special position called the number 8. The flankers are positioned right beside the second rows on either side, depending on which side of the field the scrum is at a given time. The blindside flanker is positioned near the touchline, while the openside generally occupies the position with the most space on the field. The number 8 is positioned at the very back of the scrum, acted as an extra power and the source of ball control during scrums. The back row in rugby league only contains one player, dubbed the "loose forward". This one could act as an extra out-half similar to a normal fly half and wears the number 13 on his back. The loose forward trio in union wears 6 for blindside flanker, 7 for openside flanker and number 8 for the eponymous position. The backs are generally the same, except for the naming of some positions. The scrum half in union wears the number 9, while the number 7 jersey is reserved in league. fly half occupies the number 10, while the same position can also be called the stand-off and owns the number 6 shirt. centers in union are split to inside center wearing the number 12 and outside center wearing 13, while in league the same position is dubbed the left center (number 4) and right center (number 3). The back three are still occupied by two wingers (11 and 14 in union, 5 and 2 in league) and a full back (15 in union, 1 in league). The substitutes then were given the numbers 16 to 23 in union, and 14 to 23 in league. Sometimes, shirt numbers don't really matter in rugby league, as showed by the English Super League, where players are given shirt numbers between 1 to 30, and to be used for the entire season, while also allowing the surnames of the players to be used in conjunction with the numbers. In their union counterpart, the Premiership Rugby, this practice is also used, although they keep the 1 to 15 numbering scheme, only changing the names of the players wearing it. Outside of England and during international test matches (world cup included), only numbers are used for identification.
During the gameplay itself, there are many elements from rugby union that was removed during the formation of the rugby league code. The first being rucks and mauls. As we all know, rugby union laws allow the possession of the ball to be contested every time after the tackle has completed, which involves the tackler must release the tackled player, which in turn must release the ball immediately. The forwards of both teams then bind together to push each other in order for either scrum half to safely access the ball. This is known as a ruck. A maul happens when the player in possession of the ball is bounded by teammates and opponents while still standing on their feet. This is typically happened after a line-out. In rugby league however, the tackled player is allowed to keep the possession after the tackle has completed, and the defending team must retreat 10 meters. The player then plays the ball to their scrum half by heeling the ball back to them. The main reason to this is to create a faster, free-flowing game, while at the same time deeming the existence of rucks and mauls would only slow the game down. Union fans argue that the removal of these two key elements means dumbing down the rules for the sake of creating a spectator-friendly game. League fans argue that the union code is slow in nature, and many players simply don't have the physical capabilities to play it.
The second is the number of attack phases. In rugby union teams can have as many or as little phases of play as they desire in order to score points. This means teams have the freedom to move the ball down the field with various strategies. from line breakers to box kicking, teams have variations of tactics as they own possession of the ball. The most prime example of this is when Ireland took on France during the first matchday of the 2018 Six Nations. During the dying stages of the game, after the French utility back Anthony Belleau missed a kicking opportunity, with less than two minutes to go and the score was 13-12 in favor of the French, Ireland went through 41 phases of play ending with Jonathan Sexton's game winning drop goal at injury time, bringing the score to 13-15. The Irish then went on to win the tournament. In rugby league, there are limitations to the gameplay, namely the "six-tackle law". This specific rule mandates the teams to have equal amounts of tackles in order to advance the ball. when the tackle has completed, and the ball has been played, it counts as one tackle. Teams have six tackles at their disposal, and after those six has been exhausted, a change-over occurs, meaning the attacking team must turn to defense, and the defending team may attack.
Other changes made is the scrum law. In rugby union, scrums are used as a set-piece to restart the game after a foul, usually a knock-on. The forward pack lines up with the referee's discretion, and after the position has been set, the referee will initiate the engagement with the commands "crouch" to prepare the pack by crouching, "bind" to prepare the props by binding into each other, and "set" to engage. In older days, the commands were "crouch" to prepare the pack, "touch" for the two props to touch each other in the shoulder, "pause" for a slight break, and "engage" for the pack to fully charge and engage into each other, like a literal battering ram. The scrum half then must feed the pack right down the middle, giving the opportunity for both hookers to hook the ball to their teammates behind. In rugby league, scrums are used for restart after a foul and after the ball went outside the playing area, since league doesn't have line outs. The scrum itself is not contested. The forwards would simply bind with no commands from the referee, and the ball is feed through the non-offending team's second row. Line out is the feature exclusively for rugby union. It occurs after the ball has left the field of play (dubbed "into touch") and involves both teams' forwards to line up across each other like that of a tunnel, while the hooker throws the ball in line with the tunnel for teams to contest possession. Most of the time, the opposite of the team who got the ball out of play gets the line out throw, however if it came as the result of a penalty and the non-offending team elected to kick into touch, that team is awarded the line out.
Both rugby codes use the same scoring methods, with the main difference being the number of points awarded. In union, a try is worth 5 points, with the resulting conversion adds another 2 points if successfully executed, bringing the total to 7 points for a converted try. In rugby league, a try is worth 4 points, with the converted try worth 6, one less than union, with conversion points remain the same. The referee also has the power to award a penalty try when there is an infraction occurred, in which if that foul never happened, the try would certainly be scored. Penalty try in union is awarded an automatic 7 points, with no conversion required, while in league, the penalty try procedure is a bit complicated, despite offering the highest number of points possible, being 8. When a penalty try occurs, it automatically awards 4 points while still requiring a conversion kick in normal manner. Then a penalty kick is taken on the place in front of the goal posts, regardless of the place of the foul. Best case scenario being both kicks were successful, and 8 points are awarded in total, while the worst case one is the team could only manage 6 or 4 from the penalty try itself, should either or both kicks missed the target. Penalties and drop goals in union carry 3 points each if the kick went between the posts and over the crossbar, while in league, penalties offer 2 points, and drop goal resulting in just 1 point. This, in turn forces the rugby league teams to rely more on tries since other scoring methods offer less points. But in the event of a close scoring game with one or two points difference, penalties and drop goals might be that one time that would make the difference between winning and losing a game.
The other difference between the two codes came down to the demographics. During the early inception of the rugby code, the rules at the time restricts the players to be amateurs, with no payments allowed for players after the game. This in turn forces the working-class players to choose to miss matches to focus on their day jobs, or to risk being fired just to play rugby. The Rugby Football League was formed with the working class in mind, and clubs are usually found in the suburbs. While rugby union has always viewed as the upper-class game, mostly found in big cities, and taught in the school systems. It is actually the de factomost popular code of rugby in the world, with 108 unions being official members, and 24 other unions being associate members of World Rugby. Rugby league on the other hand, is governed by International Rugby League (IRL), and only has 35 countries as official members, with 19 of them being full members and 16 affiliates. In addition, 24 other countries acted as observer members. This translates to many fans and players who talked about rugby would refer it as rugby union for most of the time. The game is widely played around the world. Heck, even my country of Indonesia has its own union, called Indonesian Rugby Football Union or INARFU (Persatuan Rugby Union Indonesia in Indonesian), although we still probably miles away from playing our first World Cup. In some places, like Australia and Papua New Guinea, rugby league is actually the most popular sport over rugby union. The Australian national rugby league team, dubbed The Kangaroos are consistently among the best rugby league sides in the world, with the same feat in rugby union is usually debated between New Zealand and South Africa, dubbed the All Blacks and the Springboks respectively.
Then, it comes down to the physicality of the game itself. Rugby union, with all of its elements, whether it's the ruck, maul, scrum, and line out, is perhaps the most physical game you've ever see. It's not uncommon to see big, bulky props shoving those tiny, twinkle-toed wingers while breaking the defense line, or even towering second rows dominating the line outs, or scrum halves running like their backside is on fire while scoring a try. The forwards must be prepared to handle the dirty work on the field like making tackles, break the line, form a ruck, bang each other's heads in the scrum, and formulate strategies during line outs. The backs are expected to be elusive, fast, and agile, as most of the tries scored came from them. Rugby league, however, are more into the stamina and explosive bursts of powerful tackles, since there is almost no physical element to the game itself, apart from the tackles themselves. In short, union players are mostly specialized in one area of the game, whether it's the strongest, tallest, or fastest. League players tend to have more stamina, as most of the time on the field are spent running around like a stabbed rat. And if you look at both teams' postures, union player are more diverse, some of them are bulked up, some are taller, and some can be considered as short-statured. League players are more uniformed in terms of height and body dimension.
In a nutshell, despite derived from practically the same code, rugby union and rugby league in reality, is two different sports, each with its own laws, fouls, and regulations. From number of players allowed in the team, attacking phases, to the removal of some elements, both codes offer different experiences to different types of fans. If you like a fast-paced game with even amounts of possession and higher scoring chances, rugby league might be suitable for you. If you like a more technical aspect of the game, with various strategies and tactics at your disposal while maximizing the breakdown, then rugby union might be your neck of the woods. Stay safe, and let there be peace in the world.
