East Group C:
Celtics: 3-1 (+27)
Magic: 3-1 (+22)
Nets: 3-1 (+10)
The Nets beating the Raptors created a 3-way tie between the top 3 teams in the group (Celtics beat Nets, Magic beat Celtics, Nets beat Magic), so point differential decides the winner of the group.
All final IST group games need to be played on the same night. Probably a lot harder to do, but Boston had the advantage of knowing how many points they needed to win by.
