Mostly, he’d be a guy that was known for his ability to score that couldn’t actually score all that well, and couldn’t do much else, either. He’d be a below-average passer, a sub-par rebounder for his position, and a lazy and often inattentive defender.
He’d probably be a ball-stopper that liked to hold the ball, survey the court, and then attack a set defense. Right off the bat, there is no question that he would have a high usage rate that was not justified by his efficiency. If you were to get into a lab and design what you would consider to be the least “Spurs” player possible, what would that player look like?
