Getting only 43 wins is likely to have you golfing by income tax day in the West. In fact, there may be a 50 win team that doesn't make it. Playing .750 ball gets them to 49 wins, still possibly short, but more likely to at least be on the bubble. I can't see them doing that, though. Their best bet at this point is to blow it up, and try for next year...see what they can get for Bibby and Artest, and start to build with Martin.
Oh, and they've only played 20 games against the WC so far. Look at the rest of the teams. SA has played 26, for instance, and most have played at least 24. If they can't make .500 with a more heavily weighted EC schedule than the rest of the West, they're ed trying to catch up playing more WC games than the teams ahead of them.
