He was a part of two Rose Bowl teams and was also a pitcher for the baseball team.[2]
Professional career
Dallas Cowboys
Kupp was selected by the Dallas Cowboys in the ninth round (116th overall) of the 1964 NFL draft as a tight end. He was converted into an offensive guard during training camp, where he made the NFL All-Rookie team after starting 10 games at left guard. The next year he started all 14 games at left guard.
Kupp became one of the original members of the New Orleans Saints, after being selected in the 1967 NFL Expansion Draft, playing 5 regular season games as a starter at left guard, before being released.
Atlanta Falcons
On November 5, 1967, the Atlanta Falcons claimed him off waivers and would appear in 6 games with 5 starts at left guard.
New Orleans Saints (second stint)
Although the rights to his contract were traded to the Atlanta Falcons, it was only one year, instead of his full 2-year contract, forcing his return in 1968 to the New Orleans Saints, based on a league ruling that long term contract players can be waived one season only (rule since rescinded). He made the Pro Bowl as an offensive guard in 1969.[5] He was named one of the team's offensive captains in 1969.
He originally retired at the end of the 1973 season, but changed his mind and reported to training camp the following year. Although he never experienced a winning season with the franchise, he was inducted into the New Orleans Saints Hall of Fame, while also being named to the franchise's 25th, 40th and 50th Anniversary teams.
