Kirk Herbstreit is a popular pre-game host on ESPN’s College GameDay and one of the most recognizable analysts in the game today, but fans on social media are not thrilled with his work this weekend.

Herbstreit, who attended and played quarterback at Ohio State, traditionally calls the Saturday night game on ABC. This week, that game features a top-25 showdown between Michigan and Minnesota.

Herbstreit is traditionally solid in the booth, but for this game, it looks like fans are calling him out for what they perceive to be a pro-Michigan tilt to his analysis.
