I'd hope to add a big to roster at the 15th spot. Can't help but think of bill Walton who really was done by the time he came to the celtics.
Bill as a trailblazer early on was one of the best all around centers to EVER play. Injuries obviously did him in
Bogut was a very good all around center until that horrible broken bone, since then he has looked very good but had an injury history.
To me at 15th spot, why not??? He can ease into lineup, if sore, sit him. He could realistically be the 4th big at times. I'd look hard at him, his iq, passing and rebounding even in limited minutes will help.
