5. Playoff Rondo needs to show up
Rajon Rondo has taken some heat for only showing up in big games, but this is the time of year when that should be a good thing. For his playoff career, Rondo has raised his point, rebound, and assist totals over his regular-season averages. It's safe to say that this is now Rondo's team, and he'll need to be the best player on the floor at times if the Celtics are going to take care of business against Atlanta.
