The 2021 Allianz Hurling League created huge debate in many areas and one of those was the number of frees award by the referees in the games. Here are some of the key numbers and trends that arose in relation to fouls and frees.
The opening round of the league saw an average of 29 frees per game, rising to 37 frees per game in week two however in the final weekend of games the average number of frees awarded had dropped to 23 per game.
Referees like Sean Stack and Cathal McCallister were on the top of the table for awarding frees by averaging 40 frees per game while Waterford's Thomas Walsh was on the bottom of the table with an average 21.50 frees per game.

Limerick's Conor Boylan was the most fouled player by winning 15 frees over the course of the league. The top six players to win frees in the league all came from players who play in midfield or in the half-forward line positions.
This highlights the combative nature of playing in the middle third of the pitch and the pressure which is applied on players in possession.

Conor Boylan was the most fouled player in this year's Allianz Hurling League
One statistic that will encourage law makers in the GAA is around the new rule brought in at the start of the League, which discouraged the dragging down of players to the ground at vital stages of a game.
On five occasions over the 30 league games a player was dragged to the ground during the final ten minutes of proceedings.

Hurling has taken action to reduce cynical fouls
This will give the GAA some hope over the coming weeks that the new rule is acting as a deterrent for teams engaging in cynical fouling during the final minutes of games.
The overall analysis of the tackling and fouls awarded during the 2021 Allianz Hurling League suggests that more clarity and detail may need to be inserted in to the rule book in relation to the free hand tackle. The free hand tackle has some crossover with the number of frees for high tackles as these frees are awarded due to players trying to perform the free hand tackle.
Players are trying to grab players to halt their momentum but they are either mistiming their challenge or the opponent is ducking down when anticipating the challenge and this results in a tackle higher up on the opposition player's body or around the players neck.
Rule 5.10 in the GAA rule book states that it is illegal to grab and hold an opponent with the hand or hands during play. But there is not the same clarity in the rules when it comes to tackling a player with the free hand using a closed fist or an open handed slapping motion to the opposition player's ball holding hand.

Joe O'Connor was one player to spend time in the sin bin during the league
The frees awarded for using a closed fist or an opened handed slap could be interpreted as a form of rough play under Rule 5.4 which states that a free may be awarded if a player is engaging in any form of rough play.
With the tackle being so complex now in the modern game and all the stakeholders in the game looking for more consistency from game to game from the refereeing of the tackle, it may be time for the GAA to review the Aggressive Rule fouls in hurling.
