Sorry Nan but with the lead on the road and your best player potentially playing like she had to, YES you take her out with that much time left in the half. Run the clock when you get possessions and the lead will not dwindle all that much if at all. Chong, Butler, Lou, Nurse and Crystal would have been fine. Especially with Collier in similar trouble. It wasn't a good move but worked out.
That team can't handle one of the core 6 being out of the game. That's why he did it. He took a gamble to try and keep the lead. It backfired, but it was a gamble that he decided to take.
He's also always coaching for March. In March, it may be that they need to play with foul trouble, and need to learn how to do it.
