ESPN College Gameday has already visited a Wisconsin game and a Tennessee game this season.
It visited the Badgers' game at Lambeau against LSU and the Volunteers' gimmick in Bristol with Virginia Tech. BTN has never in its history broadcast a game featuring higher-ranked teams than Wisconsin and Michigan State today, but ESPN played its SEC tiebreaker and is in Knoxville today.
Sparty has won 6/7 games going back to the last time Ohio State visited East Lansing. The one it dropped in that span was in the College Football Playoff against Alabama, where it scored zero points.
