He had plenty of focus when he was playing for his first big contract back in 2008.
The guy signed a big deal and then his production fell off a cliff. He's Tag with a tan.
To be fair...The first year after his big contract his numbers even improved further. But after that he just regressed or got uninterested for whatever reason. Might be coaching, his personality or a mixture...But he definately should get the hooker snapshot on his locker. Motivation for his contract year. Good play leads to more and better hookers. And less STDs long term
Another reason for his regression might be the change of defense in the NBA. He's basically only able to convert dishes and boards on the offensive glass. Thus he suffers from the 2.9 defense and lack of athleticism. Help defense real terror these days.
