NOTRE DAME FIGHTING IRISH +9 over Ohio State Buckeyes

NOTRE DAME FIGHTING IRISH +330 over Ohio State Buckeyes-----osu went 1-1 vs Oregon and lost to Michigan.   NOTRE Dame went 13-2 ATS,  lost to Northern Illinois and has the 3X Revenge.  I don't see much of a difference.  If Demeco Ryans didn't win,  why should Ryan Day win?
