I agree with that too, especially with the Heat also using Lebron James at PF too. That's why I was also interested in Dominic McGuire myself.
The Spurs still need a mobile PF/C, but next on my list would be those SF/mobile PF types, we need another one of those as well because Bonner and Blair can't play that role. That, to me, is another critical hole that the Spurs need more depth in. Diaw would be able to do it if he went back to his Phoenix weight, but other than that we have only Kawhi and SJax that can fill that role.
I think we're on the same page here, and really most of us here are on the same page, but why are the Spurs looking at small guards and slow guard/slow forwards like Kapono?
