Iowa is playing a close game at Columbus. Iowa hasn't gotten much talk as a B1G contender but they've played well pretty much every night and their losses were all winnable games. They might have beaten UW in Madison if McCaffery hadn't blown a fuse.
In other B1G news, Purdue beat Nebraska - PU is now 11-5 overall. They may be underrated.
Illinois visits NW later today. Even on the road, UI should easily take care of business if they're really a top 25 team.
