I didn't watch the last game, but was puzzled over why Sengun only got 5 minutes. I assumed it was an injury or sickness of some kind. An intentional benching is just nuts.
Sengun should play until he fouls out of every game. He should never be benched for any other reasons
25-30 minutes is the sweet spot. I expect foul trouble and conditioning to limit him from playing more minutes for now.
The simple answer is always more minutes than Green. Even the NBA rookie ladder recognizes he's better than Green. I don't think Green got all the education he needed out of the G League and should go back to get his degree.
