Iowa has the worst offense in the country per metrics and is last in the b1g. To keep it simple, I'll start off by looking at just the current b1g teams.
2023 top offenses in b1g are osu, psu, md, mi, wi, il in that order.
2023 worst offenses are ia, nw, mn, in, ru, ne, msu, pu
Even with our pathetic output, but without getting into details, I feel like we would be overall worse if our offense was literally replaced with nw, mn, in, msu, pu, or md offenses.
So the obvious takeaway for me is that it would be lovely to generate metrics on offense like osu, psu, and mi but the problem is Iowa isn't going to recruit like those guys, so it's a waste of time to consider them. That basically leaves wi, il, ne, ru. Would we be really better overall with a wi, il, ne, or ru offense?
Feel free to suggest other (realistic fits) programs as well.
