Jim Harbaugh's autograph signing last week at the M Den seemed unusual for a head coach. But apparently, there was a plan.

Harbaugh, who signed for 200 people over 1 1/2 hours and took a few photos at the end, donated his $10,000 appearance fee directly to the ChadTough Foundation, according to a post on the foundation's Facebook page.

Tammi Carr, whose son Chad died of a brain tumor in November, wrote: "Coach Harbaugh is pretty amazing! He did an autograph signing at MDen last week and today I picked up a check for $10,000 from the the MDen. Coach Harbaugh asked that they donate his fee directly to The ChadTough Foundation. People can complain about this or that....practicing in Florida or spending the night at a recruit's house. I don't care about any of that stuff what I care about is the man has a great heart and that he really gets it! He is giving time, money and creating awareness for a disease that has had a very small voice. He is using his power to make a difference....as are Coach Beilein, Coach Hutchins and many others. They are all great coaches and a great people and we are so thrilled to have their support!"

Harbaugh, who made over $7 million in his first season as Michigan's coach in 2015, reached out to the Carr family from the time he took the job. Michigan hosted the Carrs at Schembechler Hall for multiple practices, honored them on the field before a game, and Harbaugh and his wife personally offered to fly in a specialist for an alternative treatment in Chad's final months.

Harbaugh also made the "Signing of the Stars" event a fundraiser for ChadTough, which raises money and awareness to fight pediatric brain cancer (DIPG). Asking for donations, U-M helped raise more than $110,000 from that one-day event.

U-M basketball coach John Beilein also has been an advocate. He is trying to win the Infiniti Coaches Charity Challenge on espn.com -- the winning coach's charity receives $100,000. Beilein, his staff and the Maize Rage wore ChadTough T-shirts for a recent game to raise awareness.
