Jim Harbaugh's a man of his word ... fulfilling a promise he made to ink his body if they won a national championship -- and his players filmed the whole experience.
The Michigan Wolverines football team met up Saturday to receive their national championship rings ... and, JH lived up to his end of a deal -- sitting down with an artist and getting the Michigan "M" tatted on his right arm.
After Michigan defeated the Washington Huskies in the title game 34-13 back in January, Jim revealed he'd promised his team he'd tattoo their logo with the record "15-0" as a shout-out to their accomplishment.
