Memphis really has nothing to play for against Utah because they can't get higher than a 5th seed.
Houston on the other hand would drop to the 8th seed if they tie with the Lakers at 45-37 because the Lakers has a better conference record and they would tie 2-2 for the series. Wouldn't it be in the best interest of Houston to play the old Spurs verses the youthful OKC at the 8th spot. Obviously none of that will matter if Memphis eliminates Utah in the early game.
