this rule singlehandedly has ruined hockey. It takes away the ability for teams to ref themselves. Instead, they are forced to play that clutch/grab crap. Lets put it this way, if a guy tried to hold down bert, shoney would kick the crap out of him on the next shift. that guy won't tough perrault again. Now, its legal to do all that stuff. I've been saying this about the instigator rule for a while now, but i cannot seem to get to colin campbell quick enough.
another "rule" is the part time ref thing in the nfl. In fact, they might be full time now, but i remember that there was a stink about the refs having real jobs during the week so it impaired their game prep. Don't know if this is the case anymore, but if they are part time, make them full time so they can get better.
