Gobert played 38 minutes and Mitchell 36. Those are the main ones who should have gotten a bit more rest. Looks like Favors only played 25. It's possible they're limiting Favors a bit because of the neck spasms he had recently but if that's the case then, yeah, they probably should have played Udoh a bit. It's always hard to know when to start substituting, I'd imagine. Indiana isn't bad and you could certainly lose a 20 point lead in 5 minutes. I think Indiana started to sub at about 3:30ish left in the game. Quin could have started to sub at that point, probably, but it wouldn't have been a huge difference from how it went.
