Video: 'Countdown' breaks down Rondo

The "NBA Countdown" crew breaks down Rajon Rondo's huge fourth quarter in Game 7 against the Sixers and assesses what impact Rondo can have in the Eastern Conference finals against the Heat.

Magic Johnson says that if Rondo is playing well, "he can turn a whole series around. That's wy I think it's going to be tremendous against the Miami Heat."

Jon Barry cautions that Rondo won't be able to take any games off. "I don't need him to hit jumpers," Barry said, "but I need him to be offensively in attack mode all the time."

Chris Broussard says the Celtics' performance in Game 7 is "another example that when their backs are against the wall, they come to play."
