I'm guessing that Bolton's usage rate has gone after Tyrese went out? I'm surprised that it is that high, but I think it's partly born out of necessity (and lack of other offensive options), whereas I think Lindell was a bit stickier with the ball (despite a plethora of other offensive options).
Bolton's usage rate was probably higher with Tyrese around.
He's actually cooled it since the K-State game.
Kobe's looking down and smiling at that rate in the Texas game.
Nixon and Young are the ones going hog wild lately.
