There's this idea that the fancy metrics love Rondo. That's not completely accurate. His PER was 18.8 last year, and I think we'll see Thompson get there as soon as he

a) has a halfway decent coach, and

b) he learns how not to foul on every possession.

I think he has a sentient coach now, and there has typically been a drop in fouls/minute among sophomore big men.

On the surface, Rondo is better than JT and likely better than the No. 4. But looking at the context, it doesn't make sense for the team.
