The cause of death was heart failure. Webb was 78.
Webb joined the Giants in 1961 after one of the most unusual journeys by a player en route to an NFL roster. A Little All-America in 1952 at Arnold College in Connecticut – the alma mater of Giants Hall of Fame defensive end Andy Robustelli, who died on May 31 – Webb served two years in the Navy after college. In 1955, he had a tryout with the Los Angeles Rams before playing for the Montreal Alouettes in the Canadian Football League. Webb later played for the minor league Stamford Golden Bears before getting a tryout with the Giants in 1961 – nine years after his final college season.
Webb made the team and stuck around for five years, playing safety, running back and kickoff and punt returner. He played in 48 games, including a career-high 14 games in 1962 and '64. In his career, he had seven interceptions for 58 yards in returns, 13 kickoff returns for 266 yards (20.5-yard avg.) and eight punt returns for 106 yards (13.3-yard avg.)
The Giants won the NFL Eastern Conference title in each of Webb's first three seasons.
In 1961, he had 51 rushing yards on six carries, five returns for 61 yards (12.2-yard avg.) and eight kickoff returns for 156 yards (19.5-yard avg.). The following year, he had no rushing or return yards, but intercepted three passes. In 1963, Webb again picked off three passes and had three punt and three kickoff returns. He had an interception in 1964 and two kickoff returns in 1965, when he played in a career-low three games in his final season.
After leaving the Giants, Webb spent the 1966 season as an assistant coach for the Scranton Miners of the Atlantic Coast Football League (ACFL). He later moved to the Westchester Bulls in the same league. In 1971, Webb, then 37, became the head coach of the Long Island Bulls.
Webb rejoined the Giants as a scout in 1972. The next year, he was a special assistant. From 1974-78, he was the Giants' offensive backfield coach under Bill Arnsparger and then John McVay.
In 1979, Webb began a four-year stint as the Cleveland Browns' Director of Pro Personnel.
McVay, a longtime executive with the 49ers after leaving the Giants, helped bring Webb to the 49ers. Webb spent 13 seasons in the team's pro personnel department. The 49ers won four Super Bowls during his tenure with the team. Webb retired following the 1995 season.
After retiring, he enjoyed spending time with his family and traveling with family and friends.
Webb is survived by his wife, Jan, a daughter, Lisa, a son, Marc, daughter-in-law Katherine, grandsons Nicholas Allan and Maurice and a niece, Taylor Ann.
A memorial service for Webb will be held in the near future.
