you're ignoring that sec reloads, not rebuilds. georgia and alabama recruit at a level where the next first-rounder is already on the roster. their "depleted" lines would still be the best units most teams face all year. indiana won a title, but the big ten is top-heavy and soft in the middle. the sec's week-to-week physical grind is what the data never shows. florida's schedule is brutal because even the "down" sec teams have more raw talent than 80% of the country. miami is good, but they'd finish fouth in the sec east.
