The big key to this game will be Nate Robinson's defense against Jameer and Gilbert + the team's ability as a whole to defend those 1-5 pick and rolls. They do those two things and this will be a comfortable victory ... they don't and Orlando has a shot.
In a playoff series with a healthy Rondo and hopefully a healthy Perk / Jermaine, those two variables will be very much in Boston's favour, and as a result, they'll destroy the Magic.
