Here's evidence that Nate is a good coach.
It would be pretty simplistic to say that this is absolute. Our offense may improve after timeouts because we usually hand the ball to Roy after a timeout, for example. Our defense may improve...for some odd reason other than Nate that I can't think of.

According to this, the third best 5-man unit per minute was the tiny ball lineup of Blake-Jack-Roy-Outlaw-Aldridge. I hated the three guard lineup like a lot of people on this site, but this suggests that it somehow seemed to work. Nate's oddball rotations couldn't have been that bad.
This is just something to argue against all of the threads calling for Nate's head.
