Derek Jeter, hoping to fire up No. 4 Michigan for its game against No. 8 Wisconsin on Saturday, had an inspirational letter and shirt placed in each player's locker.
The blue shirt was adorned with maize logos and lettering, showing Brand Jordan's logo above RE2SPECT IS EARNED and the school's block M.
Jeter wrote, "It is my personal challenge to you all to remain humble, yet hungry, every day along this journey to achieving greatness."
The former New York Yankees star works for Brand Jordan. He graduated from Kalmazoo Central High School in Michigan and signed a Letter of Intent to pay for the Wolverines. He attended classes in the fall of 1992 before becoming a full-time baseball player for the Yankees.
Jeter attended this year's season-opening game against Hawaii with Michael Jordan, whose brand is outfitting Michigan's football and basketball teams.
