I’m a bit confused with Norm Powell. Is he really a 2 way player?

I see him get beat off the dribble. He can’t really help rebound in the paint. Maybe he makes good rotations on defense?

There were several times over the past few games where I would’ve subbed Mann or Russ for Norm just for defense.

Lue had plenty of timeouts also to enable offense / defense substitutions.

What evidence is there that Norm is a plus defender?
