Big Ten team records
Home: 98-9 (92%)
Road: 7-15 (32%)
Of course the home games tend to be against cupcakes, but most of the true road games are against conference opponents.
FWIW, #1 (for the moment) Kansas just lost their second consecutive road game.
Another result of interest. Upcoming "cupcake" Prarie View A&M just lost to Mississippi State by only 7 in Starkville. Mississippi State is 8-1 and #26 at KenPom.
OTOH, PV is 1-8 and their only win is over Biblical Studies.
