Sonny Gibbs
With no first round draft choice in the 1962 NFL Draft, the Dallas Cowboys selected Sonny Gibbs in the second round (18th overall) with a future draft pick, which allowed the team to draft him before his college eligibility was over. In 1963, the 6-foot-7 Gibbs entered the league as the tallest quarterback in NFL history (until 1991 when Dan McGwire broke the record). Being the third-string quarterback, he wasn’t activated for any game of the season. He was waived on Sept. 3, 1964.
