I answered the OP with "Stevens with the Celtics" for a few reasons, mainly because I don't think the Clippers can make it out of the West. As currently constructed, I just don't think they can win 3 series against the Spurs, Grizzlies, Warriors, etc., and I don't think they have the flexibility to make significant improvements. This has nothing to do with my opinion of Rivers the coach and everything to do with my opinion of Rivers the GM.
As presently constructed, the Clippers seem to be a "tier two" team. They're always likely to make the playoffs and challenge for a top-4 seed, but I just can't see them making it to the FInals. They have yet to go on an unprecedented run that separates them from everyone else (a la San Antonio), and none of their players have shown an ability to completely carry the team in the clutch. (Yes, I do believe in the clutch gene. Chris Paul has shown flashes of it, but he can't physically carry the team like a LeBron can.) They all have weaknesses (like DeAndre Jordan's free throws) and are overpaying role players that don't make up for the weakness well enough. So they aren't in a great position to push for a title now, and Doc's best moves so far have been adding Spencer Hawes, trading for JJ Reddick, and trading for his son.
