if i was the sabres GM, i would be offering Vanek in a trade. It's not that i don't like Vanek, but getting him the center help to be consistently amazing will cost more than raping some team that is close and has some top prospects.
This sabres team as is, can not do anything to be a playoff contender past the first round. That is their highest aspiration. and by the time we get enough pieces to have 4 adequate lines, vanek won't be who he is right now.
the more new bodies you get in here the more the players see that the writing is on the wall. and maybe they'll have a more consistent effort. but keeping a bunch of these losers and adding one or two guys for a push hasn't worked, nor will it. the lazy culture is so deeply ingrained with these guys.
