What rock have you been living under the last decade or so? How many big name FA's have we had roll through here? Toronto has not the PO's since the lockout, they are not exactly a destination that vets, looking to win a Cup, are looking at.
Gagne will have a fair number of teams interested in him and he will pick the one that gives him the best chance to win.....right now Toronto isn't it.
I'm stating Gagne won't be able to pick and choose what cup contender he goes to. So I'm not sure why you're bringing up how the Leafs aren't one. What makes you think Gagne can go to any cup contender and be a top 6 forward given he's an injury prone player and not as good as he once was.
