Twelve seconds left. Game tied in Boston. An opposing crowd ready to explode.

No problem for LeBron James

His most impressive play of the night might've been his alley-oop over Jason Terry, but his most important one was the jumper that he rattled home with 10.5 seconds left to put Miami up 105-103.

The Heat came up with a stop on the other end and were able to bleed the remaining clock out to extend their winning streak to 23 games, the second-best streak in NBA history.

On Miami's previous three possessions, LeBron was isolated on the left wing with Jeff Green defending, with LeBron attacking off the dribble. Green defended him wonderfully, challenging him at the rim all three times while the Celtics came up with important stops.

So with that in mind, LeBron hovered on the perimeter, held his dribble and calmly stepped into a jumper -- one well contested by Green at that -- and finished the scrappy Celtics.

That LeBron guy. He's good.
