Why is his extension unlikely? He is a Buffalo fan, he wants to be in Buffalo, what is stopping him from signing a new deal? And there is no point in trading him at all, we need more like him.
I also like how some people say we can flip assets for someone else, who? Almost all of these guys have trade protection and are not going to Buffalo, and the team doesn't want to trade other strong players. We need to hold on to our experienced core and add 3-4 good players to the roster, we have plenty of assets to trade, but our GM is a coward and the owner is a clown.
What prevents him from signing? The same thing that prevents most soon to be UFAs looking for a final big pay day and chance to win in similar situations. Poor team, poor management, and poor ownership. He may be a Buffalo fan but most players would rather play on a contender than the team they are fans of when they have yet to win the big prize. Especially the good ones....and Tuch is good.
