My pick goes to mike milbury (he doesn't deserve name capitalization). Mike Milbury is honestly the biggest cancer to hockey. He beat a fan with his shoe, he had a way below 500 coaching record, he was the worst GM in the history of the NHL, and now this:

I've seen Mike Milbury mentioned a few times, insofar as his comments on NBCSN when Jake Muzzin was initially injured and before the stretcher.

He said: “It’s not a bad idea to stay down and get a whistle, too, by the way. I’m not questioning his integrity here or his injury."

Matt Cooke. Self-explanatory

Raffi Torres was bad too, but Milbury has been cancer in everything he has done.
