he can score pretty efficiently based on his ath/spd/ft. you just cant expect too much production from him. think quality over quantity for guys like this... in terms of actual production, i think he could easily be a 5-7ppg guy, and could very possibly be an 8-10ppg guy, it sort of depends on the circumstances.
because of his low per, he really can't take 3s, so a -2 is in order.
