Well since you asked, per ESPN:
USC - 20
Ole Miss - 19
Arkansas - 16
Tennessee - 9
Texas A & M - 6
LSU - 13
Auburn - 13
So 5 top 20 teams and 2 top 10 teams
And they still have to face #15 Florida.
Looks like you’re from Ohio...so how many ranked teams did Ohio State play?
Oklahoma - 14
Wisconsin - 8
Nebraska - 10
Michigan - 3
So 1 top 20 team, 2 top 10 teams, and 1 top 5 team...and no more teams to play before the playoff.
Penn State was ranked 8th when they beat Ohio State.
