The last time ESPN College GameDay came to town, it was held on the University of Wisconsin?s grass practice field. But Saturday?s prime-time matchup against No. 1 Ohio State is befitting a grander forum, so the wildly popular weekly football preview TV show will emanate from Camp Randall Stadium. The show, which runs from 8 to 11 a.m. Central time and features the triumvirate of Chris Fowler, Kirk Herbstreit and Lee Corso, is free to attend.
