Before Colin Kaepernick, there was Glenn Carano. The Reno Silver Legacy’s Director of Marketing was a quarterback for the Dallas Cowboys for seven seasons, from 1977 to 1983, including two Super Bowls and a championship ring.
Carano was with the Cowboys when they pounced on the Denver Broncos, 27-10 during Superbowl XII January 15, 1978. He returned to the big show for Superbowl XIII, January 21, 1979, where Dallas lost a heartbreaker to the Pittsburgh Steelers, 35-31.
He was a highly touted player coming into the NFL. Carano was a star at the University of Nevada-Las Vegas and was a second-round draft pick by the Cowboys, being picked between running back Tony Dorsett and wide receiver Tony Hill.
Carano appeared in 36 games in his NFL career completing 21 of 57 passes with three touchdowns and one interception. He made one start in December 1981, filling in for an injured Danny White, leading the Cowboys to a 37-13 win over the Baltimore Colts.
With that single start, Carano exited the NFL an undefeated quarterback and I’ve been unable to find any other player who can make the same claim. In 1984, he signed with the Pittsburgh Maulers of the US Football League and played one season before retiring.
