His impact on the team: The Falcons never made the playoffs while Zook was on the team, but they did win a then franchise record nine games in 1973, a season in which he garnered his only Pro Bowl selection. Over his seven seasons in Atlanta, Zook was known for his durability and ability to play through injuries, never missing a single game. As a fierce pass rusher Zook was among the best sack artists in the league, but sacks were not an official sack back when he played so his total amount is unknown. He is also known for recording the first safety in Falcons history back in 1971.
On coach Marion Campbell: "Marion taught me more about defensive line play than probably all of my other coaches combined. When I played I wasn't that big and I wasn't that fast and I wasn't that strong so I had to learn to play smart to survive and coach Campbell taught me how to do that."
