The difference is that the SEC doesn’t play cupcake conference games like PAC 12 teams do. Be truthful now, would you really want to play LSU, Miss, St., Ole Miss, Arkansas. Texas A&M and Auburn, each year in your division, and Tennessee as your permanent out of division rival? Alabama plays a cupcake or two because the SEC is usually so brutal, year in and year out. Pac 12, not so much. Best team in your conference right now is USC, not Washington.
The SEC, ACC and the Big-10 all play four non-conference games, while the Pac-12 plays only three. They usually play one decent team and three cupcakes. Alabama, for example, played Kent State, Chatanooga and Western Kentucky.
Bama played Chattanooga in November. Basically an additional bye week right before the biggest games of the year. No other conference pulls that garbage. OTOH, The Pac-12 has a traditional game with Notre Dame in November.
“Alabama, for example, played Kent State, Chattanooga and Western Kentucky.”
We also played USC.
