Well, Urban hired Day (who has retained Kevin Wilson). CJ Stroud looks to be the next in a line of excellent QBs, great passer, decent athleticism. It stands to reason OSU will continue to be a machine on offense and move the ball at will except all but the most elite defenses. MN unfortunately probably will not have an elite defense given some questions in the secondary and other spots.
The chinks in the armor for OSU could be inexperience and discombobulation on offense and defense early on. Their defense in particular has lost quite a bit and may be somewhat vulnerable. MN of has their own question marks in the passing attack.
I’m not saying OSU will be “easy”, or there is a high chance of success, but there is a reasonable chance at an upset if the right set of variables, circumstances align.
