Hart is a proven commodity, no doubt. That's just it. Realistically, he'll want the most he can get. To get the most he can get, he'll have to hit the FA waters. Maybe Doug could seal him up for a bit cheaper, but he'll still run 13-15M a year (I think he could command 16M+ a year on the FA market if he goes that far, but that's me). What's the smart thing to do if you're a small market team? Pay the guy the big money to keep him, or stick with the suitable, cheap replacement and use the money you'd use on Hart to fill other gaps?
