As said, he really wasn't shafted by Komisarek and he understood and supported his decision. I think it has more to do with the way some of the players have gone about their business than anything. Cammalleri basically didn't let them in that he was planning on leaving, then called one day late in the summer and said see ya. Same thing last year with Danny Richmond pulling an 11th hour move and not telling the coaches, thus leaving them and the team hanging dry. You could easily tell Berenson was PO'ed about the way Danny went about his business because I don't think Red ever said one word about it in the media, and they never even issued a press release on the Michigan hockey website saying Richmond was gone. It was like he vanished off the face of the earth for all they cared.
I think if more players were up front with their intentions...just saying something simple like "Coach, I'm going to explore my pro options this summer" to give him a heads up...I don't think he would be as vocal about the subject as he is sometimes. Komisarek didn't have any problems, same with Jeff Jillson, Andy Hilbert (he played in the U-M alumni game about 2 days after announcing his pro intentions), and I wanna say Mike Comrie, too.
