Yeah but he's kind of been this way for his entire career. As soon as he saw it would be a lot of work to get there in Cleveland, he noped on out of there to build a stacked team in Miami. As soon as Miami was winding down and he saw that Cleveland had used the high draft picks from their inevitable fall after his exit to retool he moves back there to yet another stacked team. Cleveland winding down? Time to move to LA to bring in another stacked team. Injury to key player? Why try then, time to bail early in the 4th instead of support the team he is supposedly the leader of. Sure he's a human and he wants it easy, I get it. But I also know what he is being paid to be a baby when he doesn't get his stacked team. So **** him. Stand up and be a man and actually do the job you are being paid to do.
By the way it isn't just leaving early in the 4th quarter. He basically didn't show up at all for this game. And the is far from the first time in his career he has just taken plays or games off because suddenly they are hard.
Yes yes many players do, it's human nature, blah blah blah. If he wants to be considered as the best, then man up and play even when you might not have the easy road to the ring in front of you. Otherwise, he's just a diva.
