Kind of the same in football honestly. Unbalanced league schedules will really favor teams that get to play NW, Neb twice. And honestly Wisconsin, Rutgers, and Minnesota are maintaining pretty high rankings in metrics considering some of their bad losses. If there is an upper half team out there that gets to play NW, Neb, WI, MN twice each that's probably 7 wins right there.
Edit: Side note, the Torvik conference page for the Big 10 looks honestly pretty good for Iowa.

3 top 20 players in the league is good. If that keeps up I think Iowa is a tourney team. For the record I'm a lot higher on this Iowa team than a lot of the fans are, especially after that DePaul loss. That was one game. Connor is controlling the pace well by not turning it over and dishing it to people. CJF's percentages will come back to earth, but even if he ends up shooting 40% from 3 for the year that would be huge. And Garza is just doing it all right now.
Side side note: When you look at the conference player ratings at the bottom, man Garza has some tough competition right now. Oturu, Haarms, Jalen Smith, Teske, Wesson, Cockburn, Reuvers. Just a big man renaissance in the Big 10 this year.
