You can easily Google the stats yourself. I think this game already has explained it for you.
Here's one for you that I don't even have to look up...
LSU's finally about to lose to Alabama in the national championship game, a team they also beat earlier in the season. Oklahoma State lost to Iowa State who lost in the New Era Pinstripe Bowl (???).
LSU beat the winner of the Rose bowl, Orange bowl, and Cotton bowl.
Here's something I did look up since it's the only thing I can think of we have to compare the teams on...
Arkansas beat Kansas State 29-16. (13)
Oklahoma State beat Kansas State 52-45. (7)
LSU beat Arkansas 41-17. (24)
I mean let's be honest there's really no way to directly compare but if we're grasping at straws here Arkansas beat Kansas State almost 2x as badly as Ok St did and LSU decimated Arkansas.
LSU > Ok St? Hell I don't know. I just know they had better wins and a much better loss.
