Video: Celtics-Heat breakdown

The video above features the following from ESPN’s NBA analysts:

-- Jalen Rose's key matchup: Kevin Garnett v. Michael Beasley at power forward -- age vs. youth.

-- Tim Legler's X factor: Rajon Rondo, who in Legler’s estimation has ability to be the difference for the Celtics at both ends of the court.

"Rondo is the one guy capable of having a monster series,” Legler said. “Remember what he did in the postseason a year ago, averaging [nearly] a triple double against the Bulls in the first round. He’s going to need that type of effort for the Celtics to escape a very dangerous and very hot Miami Heat team.”

-- Avery Johnson's prediction: Celtics in 7.
