Manu Down! What's the effect?

Obviously any true Spurs fan would prefer a healthy Ginobili as the post season approaches but given the surprising effectiveness of newly acquired role players over the course of the year, I'm not ready to write this team off just yet. How does Manu's season ending injury effect this team going forward? For one thing, coach Popovich should have an easier time settling on a rotation now that he does not have to incorporate Ginobili. Secondly, the decision to give key minutes to the role players who have been most effective thus far, namely Hill and Mason, should happen immediately. I don't see Vaughn complaining too much if he is redirected to the end of the bench. No one is expecting this team to get beyond the Lakers but everyone should expect the Spurs to give them a run for their money in the Western conference finals, even without Manu.
