Priggy is only a 3rd string guard because of his inability to score. If he is a three point threat, that changes how you view him. His size is great, dribble is great, Great passer, good defender, ok speed. Couldn't score early in the year.
If a guy like that isn't Rondo fast, he shouldn't be in the league if he can't score. But if he can hit three's, that's a pretty good back up.
