Rondo is a superb defender when he wants to be, but like with all things Rondo, he is very inconsistent in his play. I think it is because he is a very emotional player and lets his emotions get the best of him, but that is just my take. It is one of the reasons I would like to move him this off season, as I don't think he has the mental makeup or consistency to be the team leader after the old men are all gone.
