Udoka holds players accountable, not himself.
This game was played at a high pace since the 1st quarter. They sustained a high intensity on defense and were in transition on offense early and often. Once they're up 19, you call a timeout and start going into your bench with high energy players like Nesmith and Pritchard, and even Kanter for post touches and offensive rebounds to keep the momentum going. When you're up 19, you pour it on and keep them running on transition, not keep your best defensive lineups in running on fumes.
At the half, I was going to post a joke about Tatum having 8 shots to Brown's 12, and setting the over/under to how many more shots Jayson would end up with over Jaylen. Tatum overtook him by the end of the 3rd quarter while Brown was on the bench and ended up with Tatum going 4-14 to Brown's 4-6. It's happened in several games, it's on Ime, Tatum, and Brown himself have to correct it. Brown is too good of a player to allow himself to be taken out of the game.
