I vote keep unless a knock-socks-off trade offer is received, which I think is highly unlikely.
There is NFW he is exposed in the expansion draft.
I have a little, nagging suspicion that all is not happy behind the scenes with the Sabres and Kane. I see no joy from him on the ice, even when he scores.
He congratulates his teammates, and sticks up for them in scrums, and plays hard -- but something seems off.
Maybe they read him the riot act after his legal scrapes last summer and told him they were going to ship him out for the first decent offer. Maybe he thought no one defended him and he felt betrayed. Maybe the rumors from Winnipeg were true and he's a self-absorbed jerk whom no one can stand.
Or maybe I'm imagining the whole thing.
But I won't be surprised if he's traded. (Although I will be disappointed, because I like his game.)
I get this feeling too, and it sucks because the Kane of the last month or so is someone I desperately want to carry our third line for years.
