at this point, I think he's looking at being a backup center until he can show he's more than that. would be fortunate to get an offer around 7-9 mill for a couple of years on a make-good deal
This is the way I see him too.
He'll probably be able to save face by ring chasing though. "What I went through in LA was horrible, no amount of money can compensate for losing, I don't even care about the money I just want to be on a winning team."
If he accepts it, he'd be a great 2nd/3rd string backup on a contender. When your team goes small you're going to sit, but if your team needs to clog the lane and slow it down you'll get some minutes. Helps that he can hit free throws too, throw him in there when a team wants to play hack-a-shaq with the starting C without losing any shot blocking.
I think he's on that JaVale McGee level of value right now. A few teams will have interest, they just won't want to pay him. You've already out earned most people in your draft class despite being drafted #17, go be the 2nd/3rd string Center on the Spurs for the vet minimum and be happy winning.
