I'm struggling to understand why there is this assumption that fines will provide players the chance to take opponents out that suspensions don't. What a load of shit.
In fact hitting a player in the pocket is a much greater deterrent than a holiday. And what about players who are retiring? Why would they be worries by the threat of suspension? And on that topic, how many retiring players go out and mame opponents? None that I can think of, which only proves how ludicrous the suggestion is that players would resort to such an act when fines are the punishment.
In any event, the system should include fines and suspensions. A match fee and a week off instead of two weeks, for example, and the money raised can go back into development or the fund for the Alex McKinnon cases.
