According to
this site, none of top-10 least penalized teams are B1G schools, but
8 of the 10 most penalized teams are conference members (Ohio State is #13).
Having said that, lots of B1G fans have been complaining for a couple of years that they seem to have stopped calling holding, including when defensive lineman get
straight up tackled from behind. As of early November, none of Ohio State's B1G opponents had gotten an offensive holding flag for over 2 years. (Ohio State ranks
134 out of 136 in penalties called on opponents.)
