I like Ohio State -8. Oklahoma's defense is built to play in the big 12, they are small and quick with most of their talent in the secondary where they return 6 of 7 starters, but Oklahoma will start a redshirt freshmen at LB and several new defensive linemen against an Ohio State offense that is built on the read option. Ohio State is young in the secondary but they have one of the best defenisve fronts and should be able to keep Mayfield in the pocket, which worrked last yearr.
