This is not what McVay said. He expressly stated that it was his decision to bring the team back to LA between the Philly and Buffalo games. His reasoning was that, with covid restrictions within hotels and also against being able to go outside anywhere from the hotels, staying out in a hotel on the road was more disruptive than going home.
Then he talked about having consulted training experts on Circadian rhythms, and concluding that a really quick turnaround trip-- flight out the night before, get up and play, go right home-- was the best way to go.
So McVay analyzed the whole thing and came up with a plan, as he always does. It worked really well for the Philly game. Now he has three more East Coast trips to try it out further.
