He'll have more suitors than you think. If a contender can get Marty as a backup they'll be salivating. That's a huge safety net. I could easily see a team like the Sharks bringing him on as a backup.
Sharks seem like they're working on bringing Alex Stalock back. I could stomach Brodeur being a backup in Chicago (good team, chance at a Cup), although I could understand if they'd rather just get somebody like an Al Montoya (Chicago native) instead. I feel like San Jose is more likely to bring in a guy like Ryan Miller to start than to bring in Marty to backup.
Just going off the top of my head......
