This year? Heck no. He's not worth the salary we'd have to dump just to make it work.
Next summer, though? I'd be all for it, on two conditions: 1. he looks better in OKC than he did in Philly (basically, if he proves that fit was the problem there, not age) and 2. There's no better options available (and I mean better players, even if they cost more assets wise. I'd rather give up a couple of picks for a younger guy than get Al for free, but if nothing materializes then he would be one heck of a return for a TPE). Not to mention, it would basically have to be part of going all in for a title
