I think, at their best, tOSU can put up a fight against Alabama. They're good enough.
Justin Fields was injured in the previous game. That definitely wasn't tOSU's best. The injury was obviously a huge concern, and the Buckeyes played to protect him. Without that dynamic dimension, all they could do was try hard.
Alabama's offense is an NFL rookie camp. I'm excited to see what Sark can make out of the parts at Texas next season, but it's clear that the 'bama roster is something special that the Horns don't have (yet, I hope).
