I like Budinger. Seems like, for the price it would take to get Iggy, who is playing pretty poorly on offense right now and getting up there in age, we could bring in Budinger, extend Aminu, and bring in a backup PG like JJ. Not that I'd complain if we went after Iguodala, but that's a better option unless we have a lot of faith in Rivers stepping up. Iggy's contract would also be harder to move in 3 years when we have to extend the likes of EG/Davis/Ryno than would be Budinger's.
I think Iggy is going to exercise his player option, so it doesn't really matter.
I would love to go after Josh Smith and then fill out the roster with top-tier d-leaguers (your Brian Roberts, Lance Thomas etc.), but if that pipe dream doesn't happen, next best thing would be getting a guy like Webster for $6-8M and then bring in a good backup PG and C.
