The only thing Perkins has to do to avoid getting his seventh Tech is keep his big trap shut when he gets whistled and don't get into unnecessary shoving matches.
I love Perkins game and what he does for the Celts but he has always talked way too much to the refs after every foul he gets.
He can still play good, hard, clean and physical defensive basketball and just keep his mouth shut and he shouldn't have much to worry about.
He can rake guys arms as they go up and bang people hard with his body, etc. He just can't lay someone out, get into a wrestling match with someone or talk crap to the refs...
So my answer is I don't think so. I think he should be smart enough to know how to play at this time with the amount of techs he has.
