It's one thing to say Tulane has a solid defense when they have played the likes of Navy and Grambling. Those teams offenses are not even on the same planet as OUs offense. I have a tough time believing Tulane will be able to do with Ohio States defense couldn't do.
Only thing that can stop OU in this game is OU. For Tulane to have a prayer, they need to hope OU comes out and just lays an egg in the week after such an emotional victory.
