Ryan is attractive trade bait. Also I imagine Jonas Hiller won't be on the team much longer (I think he makes $4M+/yr). Of course they could let Perry go as a UFA and hold on to Ryan for the remainder of his contract.
Or maybe they'll go off the reservation and trade Perry at the deadline to get something for him if it looks like he won't resign. Are there any contending teams that would be able to make that kind of deal?
I bet capgeek is full of people playing out the possibilities right now.
