(AP) -- No. 5 Michigan State has come face-to-face with the two most dreaded words left on its 2010 schedule - at Iowa.

The Spartans are 8-0 for the first time since 1966. A Big Ten title and perhaps more are still possible.

But the Spartans (8-0, 4-0 Big Ten) have their skeptics, and they are underdogs for Saturday's game at No. 18 Iowa (5-2, 2-1).

The Hawkeyes saw their outside shot at a run to the national title game dissolve with a crushing 31-30 home loss to No. 9 Wisconsin last week.
