Of course there are no guarantees but if those tools aren't used - or used even close to correctl I think that is what most people are saying. The player/coach (maybe even parent of player) is responsible for the dirty play and injury the first time. When there are a dozen wreckless fouls with many of them bordering on violent with teammates congratulating each other for injuring players and the referee has done NOTHING other than call some of them fouls then the referee becomes complicit in the carnage. Yes, it is not the referee slamming a players head into the ground, yes it is not the referee who throws a punch at someone's face -- but when the referee utterly fails to act on it then he/she has enabled those dirty players to continue what they are doing. Yes, the players and teams are the ones who should be punished but that referee needs to be retrained or find another low paying hobby.
