He's a 36 year old (soon to be 37) oft inured goalie that has struggled massively since his last injury and is having troubling adapting to the changes in goalie equipment. He is in all likelihood, done, and more so, not getting another NHL contract. That's just the reality of getting old. And at this point, he's not even an adequate backup because of his confidence issues.
So ideally yeah, the Flames find a way to upgrade the position but there's also a really good chance that nothing happens. Some of the prices are just too absurd; Treliving isn't giving up a first round pick for Howard for example. The rest of the goalies that might be available are no better for one reason or another - Anderson with his injury issues and extra year on his contract, the Avs aren't trading Varlamov, Schneider for all the obvious reasons, etc. And the folks who think that there's actually a possibility the Flames and Oilers are going to make a trade involving Talbot or anything else of note have some serious issues. No offense, but yeah, it's never happening.
