Correct and several seconds later, from a different camera angle, you clearly see Kadri's bare hand on Petrovic's shoulder with Fraser still not engaged.I have no problem admitting IF I am wrong.
Please look again at the video, at 0:40 Petrovic clearly dropped his glove, Kadri appeared to be still fully gloved and TURNING away from the fight, and up to this point I HAVE NO PROBLEM.
I will state again that my opinion is: DO NOT throw punch when the other guy is on the ice, restrained by your teammate or the ref, that's cheap shot. I know that it happens from time to time on NHL, and I would just lose a lot of respect for the guy who does it.
Kadri was engaged and willing to go. Not his fault Fraser came in.
