Katcavage joined the Giants at the best possible time, as they were a team on the rise. He would play a part in New York’s NFL Championship in ’56, and while that might have been his only title, he was a large cog of the machine that appeared in multiple title games. Katcavage emerged as one of the game's pass-rushers and did so at a time when football fans were not using that term.
Sacks were not an official stat when Katcavage played, but Giants officials believe that he had 96.5, a phenomenal number for that era.
His best run in football came in the early 1960s, where he was a three-time Pro Bowler (1961-63), which saw the first and third year of his streak seeing First Team All-Pros. Katcavage played until 1968, suiting up in 165 Games.
