I can't really get a feel for them; nor have I watched any of their games, but they are undefeated.  They seemed to have taken care of Nebraska pretty easily; however, Nebraska was without Adrian Martinez.  Seems like they have a 2-3 headed running game.

They do have a nice stretch coming up - Penn State and Iowa (with Rutgers, Maryland, and Northwestern in there) before ending the season at home against Wisconsin.

Has anyone seen them play?  Are they a legitimate challenger to Wisconsin?  If they played Michigan, would they beat them?
