This part isn't true. Dude is just lazy now, he doesn't try AT ALL. He's aware though, because he's always yelling at other players and telling someone else where they need to be/should have been, instead of just doing it himself. It's not his legs either, less minutes won't mean more effort, it's just he doesn't want to play D anymore.
LOL @ the idea of Lue benching Bron though. Let's be real here, if this WASN'T LeBron, and ust another dominant player who didn't D up, nobody would say shyt about it. He'd be the forward version of Steph Curry.
