I disagree, respectfully.
Both are built on the foundation of limiting possessions, having a strong run game, and limiting QB mobility. Iowa has always had great TEs and when we've had strong ones, we've leaned on them similarly. Both are modeled to take advantage of the "bend but don't break" defenses and go down the field in 10+ plays. Neither have been explosive, nor are they design to pass 15+ yards down field more than a few times a game.
The big difference is we've had some great RBs that have been able to keep the chains moving or break away for touchdowns. We've also had usually 1 elite WR each year. Iowa used to have a strong run game because they had a strong OL and decent backs - so same concept, just a different reason why the run game was successful. Both are very conservative in nature.
The problem is that style of offense has such a small margin for error/winning. Because you're playing to limit possessions so much, you also get fewer chances to score. When you don't have a great OL, stud TEs, or an NFL back, you get bogged down very easily.
