Lebron does that shit all the time. Gets fouled hard, foul is called, he flops and flies around to make it look worse. Most skilled athlete in the league has a history of that kind of oh-shit-look-how-hard-I-got-fouled-I'm-in-the-first-row tactics. He also plays up 'injuries' more than any player I've ever seen. It's all part of his [usually successful] tactic to get even more benefit of the doubt for foul calls, but that time he paid for his bullshittery.
It's kinda fun watching all the slo-mo replays of fouls, especially on rebounds, because there is almost always something more egregious going on in the background that wasn't being called. It's a fun game, try it.
