If Frost can recruit his system, we won't beat him.
It's unbeatable when it is executed well, backed up by a defense, and only a week to prepare.
It's an opening game and bowl game loser though.
Why? It is predicted on short, easy plays, a fast pace that limits defensive substitutions, speedy - small players (a lot more of these than big fast players), simple blocking, simple formations with multiple plays, 0 QB reads, (check with me) and big plays when the d is tired.
It's like playing against an option team. If you have two weeks to prepare, you can get your team ready for the pace with quick subs on the dl, and work out assignment football for all the matchups, and work on blitz packages to screw with the line assignments, and work on bump coverage for the wideouts. You saw it with the corner blitz on the last drive of Nebby, but the safety didn't rotate over and broke coverage.
If the defense doesn't back up the offense, the lack of at the line flexibility will sometimes kill offensive drives, and a good team can go on long drives and deny the offense the multiple opportunities it is predicted upon.
Right now, in this game, you are seeing two teams executing perfectly on offense. With Iowa's style, for Nebraska, that's a losing proposition. They need defensive stops, quickly. Iowa needs to get more subs in faster on dline, but making them take 3+ minutes to score is a winning number for Iowa too.
