Somebody is missing, somebody else steps up.

It has been that kind of season for the Boston Celtics.

So even without Kevin Garnett, their defensive anchor, their vocal leader on the floor, off the floor and inside the huddle, the Celtics weren't the least bit concerned that they would give the defending NBA champion all they could handle and win.

Indeed, the C's got big-game performances from a number of players. But no one rose to the occasion quite like Jeff Green, Garnett's replacement in the starting lineup.

He didn't just play well. Green had the best scoring game of his NBA life, tallying a career-high 43 points to go with seven rebounds.

But for Green, he won't remember Monday's game for all those points scored.

He'll instead remember the points - two specifically - scored on him in the final seconds of play by LeBron James that lifted the Heat to a 105-103 win.

James, who had 37 points, 12 assists and seven rebounds, drained a jumper with 10.5 seconds to play over Green that put the Heat ahead by two points.

After the Celtics time-out, Green drove into the lane and had the ball roll out of bounds off Shane Battier.

The officials went to review the play to see if in fact the initial ruling - Celtics ball - would hold up. It did.
