J.T. Barrett had plenty of fun at Michigan’s expense as Ohio State’s quarterback, going 4-0 against the Wolverines from 2014-17.

He had a little more fun at the Wolverines’ expense during an autograph signing Saturday at Franklin Park Mall in Toledo.

Barrett signed Michigan footballs. But he didn’t just sign them. He also put a big “X” through the Block M on each football, and next to it wrote: “4-0 vs. TTUN.”

TTUN is That Team Up North – Ohio State’s derisive way to describe the Wolverines.

Barrett is preparing for the NFL Draft and participated in Ohio State’s Pro Day on Thursday. He is projected as a late-round pick or free agent.
