The injury threat is overblown, just keep the big 3 around 25-30 mins each and there should be no problems.
Reasons to play for the win.
1. Spurs are #3 in the west right now, thunder #6, already very close to a 1st round matchup.
2. They have had problems with the thunder; the thunder already have a pyschological advantage vs the spurs, this needs to be squelched.
3. The spurs should try to keep the momentum going, because they have a chance at a higher than #3 seed. It's defenitely possible, especially with the lakers struggling w/ Gasol out. Home court advantage is a BIG advantage in the playoffs and worth making the extra effort.
4. Spurs lose this game, and it reinforces that they are having problems with
+.500 teams. This could be psychologically damaging as well.
5. There gonna be more B2B's, 10 more in all. You planning on losing those too?
