The Bulls and Raptors each have 9 games left in the season now. In order for the Bulls to make the playoffs over them, they'll need to win two more than the Raptors over those nine games [with one head to head].
At this point, the Bulls have a more or less equivalent chance of passing the Bobcats as they do the Raptors. The Bulls need to effectively gain two games on the Raptors with one head to head matchup (since they lose the tiebreak), or they need to game three games on Charlotte with two head to head matchups (if they win both they'd win the tie break).
The odds of either of those things occurring aren't too great as the Bulls have the most difficult schedule down the stretch. Every game left is obviously critical including tonight's tilt against Phoenix where the Bulls have to hope to squeak out a win against a superior team.
