The SEC is not THAT much better than everyone else. They are still the best, but the gap is closing fast.
Actually . . . they are THAT much better than everyone else. The gap isn't that big at the skill positions but on the offensive and defensive lines the talent/depth gap between the top teams in the SEC and everyone else is enormous.
That doesn't mean that every team in the SEC is a world beater but the best in the SEC is easily the best in the country.
What do you see that would lead you to believe that the gap is closing fast?
