A native of Darien, Connecticut, Seyferth was reportedly "a good, but not great football player" in high school.

[1][2] Seyferth started seven games at fullback and one at left halfback for the 1970 Michigan team that finished the season with a 9-1 record and ranked No.

Following the 1970 season, Seyferth won accolades for the work ethic that allowed him to progress from a walk-on to one of the top scorers in the Big Ten.

[1] John Hannen, sports editor of the Toledo Blade, wrote:Seyferth responds to a challenge and he wants very badly to play football ...

"[1]As a senior, Seyferth started all 12 games for the 1971 Michigan team that finished the regular season with a perfect 11-0 record before losing by one point to Stanford in the 1972 Rose Bowl.

[9] The Rose Bowl was Seyferth's final game for Michigan, and he scored the Wolverines' only touchdown on a one-yard run in the fourth quarter.

Seyferth's touchdown gave Michigan a 10-3 lead, but Stanford scored 10 points in the fourth quarter and won the game.

In December 1972, Seyferth received the Besser-Lindsey Award from Sigma Alpha Epsilon "in recognition of achievement in scholarship, fraternity and athletics.

[13] He remained part of the Giants team during the 1972 pre-season and exhibition games, but he was cut at the end of August, before the start of the regular season.
