If he really was exhausted, why run sideways with the guy, trying to poke it out from behind? Plus, if had gotten in front of him at half court he wouldn't have had to run as much as he ultimately did. He could have used lateral quickness to slow him down, or just foul him.
If he was totally gassed, I can understand that. But if he was, how could he get the ball right back and sprint down and drive the hoop for a layup?? If he was that tired he would have passed the ball up.
He cared more about his own offense and not about atoning for turning the ball over. It's a pride thing in my opinion. He lost the ball, got it stolen, and felt embarrassed so he didn't want to try to hard to make up for it and possibly look more stupid if Felton scored.
Overreaction? Whatever.
