Bill O'Brien is the only coach listed on Penn State's official roster, but the new boss continues to quickly assemble his staff.
According to the Associated Press and other reports, South Carolina assistant John Butler will join Penn State's staff. It's unclear whether Butler would coach special teams and/or defensive backs with the Nittany Lions. Butler spent the past season as special teams coordinator on Steve Spurrier's staff with the Gamecocks.
The Philadelphia native is no stranger to the Big Ten, having coached Minnesota's special teams and linebackers from 2007-10. I covered him a bit with the Gophers and was impressed with how he developed players. He worked alongside new Penn State defensive coordinator Ted Roof in Minnesota during the 2008 season.
If Butler indeed is named Penn State's special teams coach, it will represent a departure from the past, when Joe Paterno assigned different elements of special teams to his assistants rather than having a coordinator.
