I don't see how anyone could have expected Embiid to play any better than he did. He will probably be a little better next game, but not enough better to change things all that much. If BOS plays well, plays their game, they win.
As to our bigs, I was surprised to see Garza get as many minutes as he did. The three big rotation worked pretty well:
Queta 17.4 Minutes
Vucevic 18.9 Minutes
Garza 10.9 Minutes
Only 0.8 minutes with none of these 3 on the floor. These 3 combined for 16 pts and 19 rebs (4 ORebs). Also 11 fouls but just 1 turnover. Garza and Vucevic can hit the 3 so the defense has to adjust. Queta protects the paint much better. I like how they are managing this rotation.
