Every NBA season brings turnover among the playoff teams. Some of the lower seeds drop out as stronger teams take their places. Sometimes, the leaders of the pack cede from the playoff picture due to injuries or age.
This season will see at least a few teams from last postseason sit at home watching other teams run through the bracket in their stead. At least one team—the Chicago Bulls—is already sure to miss the playoffs due to a key player being injured. The loss of Derrick Rose for most of the season will be too much to overcome.
Player movement will affect the prospects of at least one team (i.e. the inevitable trade of Dwight Howard will kill the Magic's chances).
Following is a list of teams from last season that are already seeing the writing on the wall.
