Nolan and Enoch are our only true centers. And Enoch is still finding his way. Phil is also the best defensive center on the team. Last night he was very effective defensively and rebounding. That's why Facey didn't get much time at the five.
Miller, last night, was are only consistent offensive option last night. That's why Facey didn't get much time at the four.
It was just the way the game fell last night. Some nights KF will be superior option and play more minutes.
