good posts...
I rarely give out T's and only one to a coach and never to that one I mentioned. If I do give him a T it will be deserved but no there will not be a clean slate. Refs might let something slide the first game and give warnings but it adds up and no reason to let a coach continue his behavior. Some coaches and refs know each other and T's are no big deal because they respect each other(somewhat

) but this coach is just a dick.
so if he doesn't show the refs respect then yeah I'll T him up. If another coach did the exact same thing but it is the first time I'm reffing one of his/her games I might pass on a T but not with someone I've had issues with in the past.
Another thing. When I first started out I had other refs sometimes say "watch out for this coach", don't be afraid to give him a T" etc. I'd rather them not say anything and I'll be my own judge. So if I'm working with a partner who hasn't had the coach I'll keep my mouth shut and if I have the same coach I mentioned I won't bring up that incident but that's as far as my clean slate goes.
