I like the idea of Nogueira coming to SA but having seen a lot of the mock drafts across the internet, they have him going in the range you spoke of (#24-27) or even earlier since he's caught the rest of world's attention. The only way I believe the Spurs have a chance at Nogueira is to trade up in the draft. Otherwise, at #28, it's the best that's still available in my mind.
