I hate to see a player with an important skill walk away for nothing and Sully was the team's best rebounder last year. But how much will it cost to retain him?
I'm sort of hoping that the rest of the league is seeing an undersized PF who doesn't provide rim protection and can't shoot 3's and he doesn't get any offers. Then the C's can get him on the cheap, something like $5-7 mil. I'm hoping the team has upgraded enough so he's not starting next season but his rebounding, I think, is a commodity worth hanging onto off the bench.
A few years ago Greg Stiemsma was out best shot blocker...but we let him walk for nothing, and I don't think many of us have looked back.
Being really good at one thing doesn't make somebody a must-have! It's pretty easy to replace guys like that. It's the guys who are good at a lot of things that are difficult to replace.
Sully is an excellent rebounder, a good passer, and that's really about it.
I'd bring him back for anywhere up to about $5M a year as a backup PF - similar money to what Jerebko is on - nothing high enough to really threaten our cap situation for the future. Any more then that I'd probably let him walk.
He's just too big a liability in too many way. His consistently terrible play in clutch situations is a deal breaker for me - you can't can't afford to play him at the end of games, or in any meaningful games (playoffs, etc).
