The average ball in play time last season was 54’ 30”. I wouldn’t want 18 minutes injury time each half and then another 6 mins extra IJ due to the ball out of play in injury time and then another 2 mins extra extra IJ. Each half would last 71 minutes, a match kicking off at 3 would finish just before 6pm.
I’m not a fan of these lengthy injury times that have come into the game myself. Players are using it to add game breaks into the match and the refs are giving fewer cards for time wasting. There’s a clue in the term “injury time” telling us what the time added on is in lieu of.
