As hyped up as the Magic and Trail Blazers benches are, the Spurs bench is the deepest in the league.
With respect to Finley, when he returns he should no longer be in the rotation. Yeah, he offers more size as a backup small forward than do either Ginobili or Bogans, but the reality is the fourth wing spot had come down to Mason and Finley and Mason is just a better, more versatile player at this point in their careers. Finley can only make spot up three's, or come off a pin down for a catch-and-shoot at the pinch post. Mason can shoot better off the dribble, handle/create better and he's quicker as well as slightly better defensively.
