I agree with KO! He has ZERO confidence in his shooting! Until he gets that shooters mentality, he's a liability.
In his defense, however, he and Sully have been singled out by officiating as weak defenders, and therefore targets for constant fouls----many of which are bogus! It's what officials do! They can't foul out the stars, so they pick on guys that aren't, or second and third stringers! It's no secret!
On that note, watch Marcus Smart. Even as a rookie he gets away with fouls constantly, because of his reputation as a great defender! It's just the way the NBA has always been----poor defenders, and non stars are gonna get the majority of fouls!
The way, as a team, to beat this is to play ultra aggressive defense, as they did in the second half the other night! It's the way the old NY Knicks used to play D back when Doc played with them. Starts out bad, but after a short time the officials get tired(or embarrassed) by calling so many fouls, and the the defense becomes crazy good!
