One more point about Lanning and defense. At Georgia, competition was stressed in all position groups and I am told that practices were extremely physical. But so too was the TEAM ethic. Kirby and Lanning got the defense to always pull together and move to the ball in systematic ways.
In fact a good friend, who is a big Alabama fan, paid Georgia's 2021 defense an immense compliment by saying that that unit played like a well-coordinated organism. Lanning was not the only brain child here. Kirby's defenses at Alabama played like that, and Georgia also had the good fortune to have Will Muschamp, a stellar defensive coordinator everywhere he ever was, as a planner and defensive analyst. So commentary in this article suggests to me that Lanning and Lupoi are working to install exactly that kind of climate in Eugene.
He is a players coach and, if the if team leaders like Sewell and hopefully the alpha players on offense buy in, the rest will take care of itself.
