The Calgary Flames will have a handful of unrestricted free agents after this season. Deryk Engelland and Dennis Wideman will likely be gone; at least one of Brian Elliott or Chad Johnson will probably stay.
But it's Kris Versteeg who's the most interesting upcoming UFA. Almost out of the NHL this season thanks to insurance complications preventing him from going to Switzerland, he ended up signing a PTO with the Edmonton Oilers.
