1980-81
Eddie Johnson and Dan Roundfield were starters for the East from an Atlanta Hawks team that was 19-34 at the time of the game.
1993-94
Derrick Coleman and Kenny Anderson were starters for the East from a New Jersey Nets team that was 22-24 at the time of the game.
-Also worth nothing that in 2007, Dwayne Wayde and Shaquille O'Neal were starters for the East from a Miami Heat that was 26-26 at the time of the game, but the team was 23-25 when they were announced as starters.
