I don't share the optimism.
The probable starter at qb has limited mobility and is fragile with a multitude of injuries under his belt. Making it through a season seems unlikely.
Unless Kirk hands over the keys entirely to his new OC, we'll see more of the same on the offensive side of the ball. Specifically one of the most adynamic offensive teams in power5 football. While Iowa managed to win 10 games with multiple close, low scoring affairs the odds are not good to repeat that feat. Could 10 wins happen? Sure. Is it likely that they'll get to double digits in wins? No.
