I agree with your point, but there is a big difference between a super vague “Iowa has potential/looks improved” and an “I think Iowa will challenge Wisconsin for the division title until the last weekend of the season” (which is what at least one of the BTN analysts believed).
Not saying to crown Iowa based on this, but there is reason for thinking Iowa could be really good this year.
Iowa and Wisconsin are the only 2 decent teams in the West, so you'd better hope Iowa is right up there with Wisky in the West. Anything besides a 1st or 2nd place finish in the West is embarrassing.
