If they really want to play the speed game that they keep mentioning, there's no way they walk away from Kane. They may have to do it at the deadline, but for now, it's time to see how this style will work with these guys.
As for the trade, I do like the thought of a finisher like pominville being able to take a few passes from eichel occasionally. I'm sure he's destined for the third line role, but he can fill in at spots and also the PP.
