Again I ask: who actually pays these fines? And are they tax deductible?
Everyone assumes it is the players (and the Ryan Matterson fine fiasco may confirm it) but I'm sceptical. (I'm sceptical about most things these days!). I reckon the employer would pay for most of them, like they do in real life.
I wouldn't want to have my pay docked for unintentional mistakes. What other profession does that?
Mistakes happen even when you are sitting in an air-conditioned office with all the creature comforts and AI assistance. Footballers are playing in a 'furnace' where pressure mounts and fatigue sets in. Mistakes are part of the profession.
