I seriously don't see that happening, they've already had more than enough chances to pull off at least one win, and if they lost by that margin at home, there's not much chance they'll win the next four games. Compared to the Suns at least, the Spurs have them beat in most areas and one or two star players won't matter if they Spurs can outclass most, if not the rest of the team.
I'm guessing it's either gonna be 4-1 or a straight sweep for the Spurs. I'm really interested in seeing how they'll do against the Hornets, who I think pretty much have their series locked up.
