I think Tyson Chandler is worth looking into. I'd prefer to see what we have in Mickey before going for him. That said, I for one value the 2nd rounder from Philly very highly and am not interested in giving that up.
I'm not too worried about any decline shown in his play so far, I think he'd be an assert for us (at least short term). More concerned about future financials, assets we give up, and injury concerns. Also I think he has negative trade value, so that's very concerning for me.
But it's not a bad idea to study him as an option. But as of now, he's not the first option I'd look into. I'm also quite comfortably heading into free-agency with what we have.
Gun to my head, I say stay away from him. But not opposed to studying the situation.
