I'm not arguing 1-3 SEC is better than 1-3 in the B1G, I'm arguing that 4-12 in the SEC is overall better than in the B1G. The B1G has a ton of garbage. I'm also not entirely sold on IU. I'm also not saying the SEC teams are flawless powerhouses, but schedules like OSU and PSU's are hard to come by in the SEC. Florida is on their 4th straight top 10 opponent and still have UGA, Ole Miss, and Tennessee left on the schedule.
I won't die on this hill, it's just my opinion. But I do agree there are no unbeatable super teams out there. Every team has a flaw or two.
