Seymour enrolled at the
University of Michigan in 1966 and played
college football as a
defensive end for the
Michigan Wolverines football teams under head coaches
Bump Elliott and
Bo Schembechler from 1967 to 1970. As a sophomore, he started all 10 games at defensive end and one game at offensive end for coach Elliott's final team—the
1968 Michigan Wolverines football team that compiled an 8-2 record and was ranked #12 in the final
AP Poll. Seymour led the 1968 Michigan team with 92 tackles, including a career-high 17 tackles against
California in the first game of the season. At the end of the season, Seymour was selected as a first-team defensive end on the
1968 All-Big Ten Conference football team. Seymour missed most of the 1969 season with a knee injury, appearing only briefly in one game against Michigan State. As a senior, Seymour started seven games at defensive end, while his cousin
Paul Seymour started nine games at
tight end, for the
1970 Michigan Wolverines football team that compiled a 9-1 record, allowed only 90 points on defense (9 points per game), and finished the season ranked #7 in the final UPI poll. He also earned Academic All-America honors in 1970. ==Later years==
