It will be tough for the Spurs to get by the Pistons come June.
If they end up meeting again for a NBA Finals rematch, the Pistons will be very confident, winning both games in the regular season.  Chauncey Billups was interviewed on Quite Frankly with Steven A. Smith, suggesting that the earlier playoff rounds, especially the Eastern Finals versus the Miami Heat last year tired them out in the Finals.

As much as some colleagues, friends and family of mine prefer the Pistons over the Spurs if they were to match up again, I think there are two factors that will go to the Spurs advantage.  One being, the Spurs have a much deeper bench, and with a minute to go, in a tight ball game, they have a few more weapons to rely on offensively than the Pistons do, and they have the one true superstar that gets calls from referees in Tim Duncan.
