im goign to guess with the sprained right ankle a month agoto start, and now with the other one sprained, its worse.
Defense is all about cutting and lateral movment, and its no secret he's got a bad ankle, and while its not so bad he can't play on it, he's made no bones about the fact that he is having trouble cutting when asked about it.
and now he has two, tough to play defense without that ability. He doesn't even full court pressure right now, and i don't think its laziness, its an inablity to stay with guys cutting left and right and making him plant.
