Half our team was intimidated by taunts all of last year. Megna and Zolnierczyk were the worst offenders.
Orpik wasn't, but judging by what happened to him, he probably should have been.
Bissonnette barely played for Phoenix (which shouldn't be a knock on his abilities...his metrics are slightly better than Gibbons' over his 5 or so years there, without the whole "too small and soft to play" thing), but when he was in there, he was very much the "you go after my guy, I go after you" type. Ran his mouth a ton as well, which the Penguins have missed since Talbot and Rupp went elsewhere.
To my knowledge, Biss is not the Tanner Glass "I'm a light heavy, you're a light heavy, I haven't had a fight in 8 games and the score's 0-0" sort. At least he hasn't been in the NHL.
