[1] Under Carr, the Michigan Wolverines compiled a record of 122–40 and won or shared five Big Ten Conference titles (1997, 1998, 2000, 2003, and 2004).

Born in Hawkins County, Tennessee, Carr moved with his family to Riverview, Michigan when he was ten years old.

[2] Carr's picture is still on display in the Riverview Community High School gym lobby, where he quarterbacked the Pirates to an undefeated season in 1962.

Carr had originally played under Dan Devine at Missouri, following fellow Riverview graduates Woody Widenhofer and Bill McCartney.

Carr transferred to Northern Michigan when the man who chiefly recruited him to Missouri, Rollie Dotsch, was named head coach.

Carr was named Michigan's interim head coach on May 13, 1995, following the resignation of Gary Moeller nine days earlier due to off-the-field trouble.

His very first game as head coach, at home against Virginia in late August 1995, was at the time Michigan's largest-ever comeback win, from 17–0 down.

The Wolverines concluded that season with a win over Washington State in the Rose Bowl, after which Michigan was named national champions by the Associated Press.

During the 2003 season, Carr joined Yost, Bennie Oosterbaan and Schembechler as the only coaches in school history to serve for more than 100 career games.

The Wolverines won consecutive Big Ten Conference championships in 2003 and 2004, earning the school's 18th and 19th appearances in the Rose Bowl.

The Gators were led by head coach Urban Meyer and Heisman Trophy winner Tim Tebow.

His teams won five Big Ten titles and the 1997 national championship after beating Washington State in the Rose Bowl.

Carr is also cohost, with WXYZ-TV sports director Tom Leyden, of the Detroit ABC affiliate's college football pregame show, Big Ten Ticket, which focuses primarily on the Wolverines, the Michigan State Spartans and other Big Ten football teams.

[10] In 2015 Carr's grandson Chad died at the age of five of diffuse intrinsic pontine glioma, a rare and difficult to treat cancer.
