Happy Mother’s Day to all of the moms out there. Sunday has been busy on social media, with beautiful Mother’s Day tributes being posted on the web left and right.

Several college football players and coaches have expressed their gratitude toward their moms, but in typical Jim Harbaugh fashion, the Michigan head coach went above and beyond the norm.

Joe Boozell has been a college basketball writer for NCAA.com since 2015. His work has also appeared in Bleacher Report, FOXSports.com and NBA.com.

Growing up, Joe squared off against both Anthony Davis and Frank Kaminsky in the Chicagoland basketball scene. You can imagine how that went.
