smart looked on the video to be an outstanding player. keeping him makes lots of sense.
but, i dont know whether he would be a good pairing with rondo or not. both play good defense and rebound well, a definite plus if both guards do that.
but...they have similar offensive games in that neither are good, reliable outside shooters. both cut to the basket for much of their offense. i worry that nba defenses would be able to play off them on the perimeter. defenses may just say "go ahead and shoot" to both of them, sag off, and take away the penetration.
honestly, if the celtics draft smart i think rondo may be moved.
