His favorite pass is way too risky to be effective on a consistent basis. Rondo is good at delivering the ball on the numbers; but when he tries the behind the back or cross court bounce stuff his effectiveness goes way down.
Pretty disappointed that he sees his claim to fame as being all the flashy stuff he does. That is not what makes him a great point guard and that is not what he should be teaching young players. They will learn that on their own.
He gets bored way too easy that is his biggest weakness. It takes someone like KG to get him engaged half the time when he looses interest.
