Aaron Gordon is a defensive 3, at least

The Numbers

Aaron Gordon’s defensive reputation is growing. The Orlando Magic already put him on the best perimeter player in most games and he is a key part of the Magic’s defensive strategy.

Gordon is possibly the best perimeter defensive player on the team. He is giving up 41.2 percent on shots overall, the league average is 45.2 percent.

This is an imperfect measure of course. NBA.com Player Tracking cameras credit whoever defended a field goal attempt as the closest player to someone who takes a shot.

It does not always tell anyone exactly who had responsibility for whom defensively.

But there are some numbers that might suggest Gordon is not as strong defensively as the eye test would suggest.

According to Basketball-Reference, Gordon has a -0.4 defensive box plus minus. Meaning his contributions make the Magic 0.4 points per 100 possessions worse than i fhe were an average player. If this keeps up, it would be the first negative box plus-minus of his career. Past the midpoint of the season, he is on pace for fewer defensive win shares than he had last year.

Yet, observationally, Gordon has played strong defense. And perhaps unlike last year, he is consistently defending the best player on the opposing team. It was Gordon locking up James Harden, Andrew Wiggins, C.J. McCollum and Kevin Durant.

For a 21-year-old, that is very impressive. There is no reason to believe Gordon cannot get better. And his strength on defense is part of why the Magic felt comfortable moving him to the perimeter.
