Keeping somewhat with the current philosophy, I would start Blake/Roy (Roy as PG) and Rudy/Bayless (Rudy as PG) in the second unit. When Bayless gets better, you can swap places with Blake or go to a three guard rotation.
My top PGs
Rudy (can push it or run the half court, great vision, good handle)
Roy
Blake
Sergio/Bayless (but Bayless gets my vote because he does non-PG things much better than Sergio)
