Wouldn't surprise me if Texas plays flat (tweener game, early start, etc.) but I do feel like they are getting their "mojo" with Ewers back. Also wouldn't surprise me if the culture comments we have made the last year or two after the game might give the Horns some motivation. That and the blowout loss we gave them last season.
It's still a "nobody knows" thing.
Nobody knows if they will continue to mail it in some games when a team gets physical, or if they will gain the physical edge any team needs to be elite.
They can do it against OU any year, they played really physical and hard against #1 Alabama, but it's been really hard for them to do vs unranked teams or teams without a huge brand.
That said, I'm talking about this 13 point spread. There's absolutely no way ISU wins outright unless they have a total revelation and revolution of the offense in one week.
