VIDEO: LeBron James opens up Game 5 with monster alley-oop dunk

Well, this is one way to kick off a game.

It took all of 54 seconds for LeBron James to get on the board in Game 5 of the Eastern Conference finals on Wednesday, as he ran around the right side of the court to throw down a precision alley-oop pass from Mario Chalmers.

Notice how the backboard's left shaking until the end of the video.

If you need a new desktop background, LeBron's got you covered.
