To make matters worse for any team in the West trying to catch Iowa, Nebraska has emerged as potentially the 2nd best team in the West but Neb already has 3 conference losses. So while Neb really has no chance, they could at the same time, end up help killing any chance Minn, Pur, or Wiscy have for a title. Not to mention maybe NW and ILL sneaking in an upset here or there.
The West standings could end up similar to 2018, where the division winner finished 8-1 and 3 teams tied for 2nd at 5-4.
