I can help out with the stats. But first, OSU and LSU are both great teams.
OSU opponent winning %: .563. Beat #13 and #20 by a combined 80-7.
LSU opponent winning %: .545, which includes an FCS team (OSU doesn't schedule FCS teams). Beat #10 and #11 by a combined 65-48.
Committee is valuing schedule and play on field (both sides of the ball).
By comparison, Alabama's combined opponent winning % is .391, worst in the Power 5. Alabama has their FCS opponent coming up on 11/23 aka chickensh** Saturday.
You are correct that a loss by Bama should hurt them more (and maybe it will with this Committee), but ..... Bama. You know what I mean.
Go Tigas!
