It's simple. In the initial rankings to start the season, the SEC had 9 teams in the top 20. The B1G had 4. Therefore, any SEC conf win was considered a great win and any loss wasn't a bad loss. Even though LSU lost to USC and Texas A&M lost to ND, it was considered "good" losses at the time due to high rankings that didn't really hurt them. So we've been fighting the inaccurate and outdated SEC bias in the polls. Texas got MASSIVE credit for beating Michigan. Alabama got big credit for beating Wisconsin by the exact same score as Iowa did.
The point is, I hope we get SEC teams in the playoffs. Overrated.
