Ok, but who's minutes is he taking? He's not a 4. I am fairly sure that part of the reason he bolted was that Ollie was not planning on using him as an outside-in small forward, just as he didn't with Larrier (and we currently don't with Polley). The position Vance would insist on playing is currently being manned by Vital and Sid as backup.
It's a roster construction issue again. I am sure he would help, no question, but he wouldn't help nearly as much as somebody who could (and wanted to) play the 4-5.
