Harbaugh, who played defensive back for the RedHawks in the 1980s, earned a place in his alma mater's "Cradle of Coaches," which recognizes the school's tradition of coaches who have passed through the university before winning a championship at the NFL or collegiate level.
Harbaugh's statue now rests among legends like Paul Brown, Bo Schembechler and Weeb Ewbank.
The Ravens also had a strong contingency of support for the statue's unveiling. General manager Ozzie Newsome, president Dick Cass Sr. and others traveled to Ohio to support Harbaugh.
"I just feel overwhelmed and stunned a little bit with the fact that people would take the time to come on down," Harbaugh said. "That this is something they would want to be part of means more than anything I could ever express."
