Well we disagree on TCU. I think that’s a terrible example.
Everything else the same, if TCU had Georgia’s roster, they would have boat raced Georgia. Talent was the difference. It had nothing to do with TCU’s offensive system.
TCU actually supports my point. They were able to dramatically outperform their talent level, beat an elite team in Michigan, and make the playoffs because of the system they ran, not despite it. If they didn’t run an air raid, I doubt they go undefeated, make the playoffs, and and beat Michigan.
