The Calgary Flames' roster appears to be mostly set. If anything, they now have to cut down players, rather than add more; particularly in the forward department.
Defence, on the other hand? The Flames may have fixed their top four woes by adding Dougie Hamilton, but there's more that can be done, and some high profile, quality defencemen still left on the open market for the taking.
But here's a pretty big problem to adding another high profile defenceman (i.e., not David Schlemko, although he'd be great, too): the salary cap.
It's not July 1 anymore, though.
