Found this little bit of info on Rittenberg's blog:
8. A family affair for Poseys: Ohio State wide receiver DeVier Posey squares off against his older brother, Julian, a defensive back for Ohio, on Saturday in Columbus. It's one thing for brothers to play on opposing teams, but the Poseys likely will be matched up directly against one another. DeVier Posey has been excellent so far this season, recording eight receptions for 146 yards and two touchdowns. But Julian Posey can hold his own -- three pass breakups and a 38-yard fumble return to the end zone this year for the Bobcats -- and he knows his little brother better than anyone. Said Buckeyes coach Jim Tressel: "I told DeVier, 'If big brother shuts you down, it's going to be a long lifetime for you.'"
This will be a nice little matchup to pay attention to on Saturday.
