Jaynes accepted a football scholarship from the
University of Kansas. During the early 1970s, he broke virtually every passing record in Kansas history. When he left Kansas, he was first in passing, with 5,132 yards. This record held for ten years until broken in 1983 by
Frank Seurer. He also left Kansas with the record for career passing
touchdowns at 35, which held up until the 2007 season, when he was passed by
Todd Reesing, who would shatter the record with 90. Jaynes' most memorable game was in 1973 against SEC power
Tennessee, when he completed 35 of 58 attempted passes for 394 yards in the 28-27 loss. In 1973 Kansas finished 7–4–1 and went to the
Liberty Bowl. Jaynes finished fourth in the voting that year for the
Heisman Trophy behind winner
John Cappelletti,
John Hicks, and
Roosevelt Leaks. He also finished ahead of future two-time Heisman winner
Archie Griffin. Jaynes is, to date, the only Heisman Trophy finalist in Kansas football history. He's one of 3 players to receive votes, along with
