Lucas was known more for addicts I always thought than over eaters. I suppose food is an addiction for some. I hope he gets in shape, he can rebound at the NBA level. Trouble, is he simply lacks the athletic base to be a NBA defender. He is slow, I mean moving like pond-water slow.
Getting in shape might improve his play some, but it won't make him a leaper or change the ponderous foot-speed. I think he would be better off on a team that does a lot of half court offense. But I would be happy, if he lost some weight and at least tried to play D, not take stupid threes and make a little effort on defense. His attitude is what has always irked me the most about him. He comes across as lazy and lethargic, when he is not rebounding or shooting. He took tons of plays off on D, does not always run the court. That needs to stop if he gets in shape.
