I'd think he would have to consider the Sabres as a decent option. No NHL goalies signed after this season other than UPL who is still very young and is probably going to be a back-up for at least a couple seasons. Some young goalies in the system but no one who's ready to become the starter so he would definitely get the lions share of the games I would imagine, which seems to be something he wants. Gives him a chance to start fresh on a new team with a very young core and an abundance of prospects ready to make the jump in the next year or 2. Also gives the Sabres a little more certainty in goal for the next few years if they are able to sign him for a 3 year deal or so, could be good for both sides.
Can't imagine the Sabres would say no to parting with a 7th for him or a B tier prospect like Pekar or Costantini.
