Scouting report on ND, based on stuff I've read:
They have a really good OLine and maybe the best TE in the country in Michael Mayer. QB Tyler Buckner is making his first start but played a decent amount last year. He's not Braxton Miller, but is a very good runner. Their WRs are maybe the weakest part of the team.
They have a great pass rusher in Isaiah Foskey a good corner in Cam Hart and a good safety in NW transfer Brandon Joseph. Rest of the defense is experienced and solid but not spectacular. The CBs behind Hart seem a little week,
I expect OSUs D to be improved, but this combo of Oline/running QB/TE will cause trouble. ND will definitely move the ball. However, unless they allow Foskey to take over the game, ND doesn't have the DBs to slow down OSU. I think it's a relatively close game throughout, OSU pulls away 45-27 in the end.
