Badgers center Travis Frederick has decided to skip his senior season and enter April's NFL draft, a source close to Frederick tells ESPN colleague Joe Schad. As I posted earlier today, ESPN's Mel Kiper projects Frederick as the nation's No. 1 junior center. Kiper had Peter Konz in the same spot a year ago and Konz opted to skip his senior season with the Badgers. Konz was selected in the second round by the Atlanta Falcons.
