Passage: After attending Canton McKinley High School, where they won the 1981 Ohio High School Athletic Association football championships, he went to the University of Michigan where he became the only freshman varsity letter winner on the football team in 1983. Rivers, who wore #13 as a Wolverine, started 32 consecutive games until a shoulder injury caused him to end the streak. He posted six interceptions in his Michigan career, including one for a touchdown. Another one during the same season was a game saving interception in the 1986 Fiesta Bowl in a 2723 victory over the Nebraska Cornhuskers football team. Rivers started 12 of the 13 games his senior season for the Big Ten Conference champions and was one of three All-Americans (along with Jumbo Elliott & Jim Harbaugh) that season as the team went 112 and was invited to the Rose Bowl. Rivers once had 17 tackles and an assist as a sophomore defensive back in a game against the 1984 National Champion Brigham Young Cougars football team in the 1984 Holiday Bowl. 17 tackles continues to stand alone as a school single game record.
