The currently ongoing Iowa/Nebraska game has no impact on seeding. Iowa will finish alone in sixth place and Nebraska will finish alone in 13th place either way.
If Wisconsin wins they finish alone in fourth place. If they lose they tie with Maryland for 4th/5th. Wisconsin loses that tie.
Depending on whether they win or lose tOSU will either tie with MN for 7th/8th or tie with IU for 8th/9th. Ohio State wins either tie.
