PTOH, they lost to Michigan by 4, at Purdue by 8, to Illinois by 8, Michigan State by 4.
However they also lost to Indiana by 41 and Pitt by 34.
In short, they can keep it close against a very good team and get blown out by a lesser team, but they haven't shown they can beat even a reasonable team.
