I was listening to the "4 to 6 with A and B" podcast on the Athletic and Bill Landis mentioned that there were clips of Steve Sarkisian's coaching clinic trending on Twitter.
Bill said (I'm paraphrasing) that Sark spoke to the audience that no one sits in Cover 3 all day, which is exactly what we did in the game on Monday.
I did a little search to find the coaching clinic, and I found this video (40min) and summary write-up.
