According to the current standings, 1 more win/Minnesota loss clinches playoffs for Denver and 2 wins/Minnesota losses clinches playoffs for Memphis. T-Wolves would have to win out and hope for Memphis or Denver to lose 6 of their last 7 games. I don't know the tiebreaker status of Minnesota over Mem/Den so it may be only 5 losses. It is really moot at this point though if the T-wolves are struggling against teams like the Atlanta Hawks.
Looks like every series in the Western conference will be worth watching. I doubt there will be any sweeps unless Memphis breaks down against Phoenix. Denver-SA is gonna be exciting to watch. That could go 7.
