Gregory Lynn Cook (November 20, 1946 – January 27, 2012) was an American football quarterback who played two professional seasons, in the American Football League (AFL) and later the National Football League (NFL). He played college football for the University of Cincinnati and was selected 5th overall in the 1969 NFL/AFL draft. Once considered a rising star for the Cincinnati Bengals, he had his pro career prematurely ended by recurring shoulder troubles. In 2007, NFL Films named Cook as the number one greatest NFL "one-shot wonder" of all-time, describing him as one of the biggest "what-ifs" in league history, in the seventh installment of its program NFL Top 10. Early career Cook lived most of his life in Chillicothe, Ohio, where he played baseball, basketball and football at Chillicothe High School. He played collegiately at Cincinnati, once throwing for 554 yards in a game. He was drafted by the Cincinnati Bengals in the first round of the 1969 NFL/AFL Draft after Bengals coach and founder Paul Brown saw Cook's performance in the Bearcats' come-from-behind, 23–21 victory against Miami University in Bo Schembechler's last game before he left to coach at the University of Michigan. Brown had attended the game, but left when the Miami Redskins' lead reached 21–6. "That quarterback. That's our draft choice," said Brown after seeing film of Cook's rallying performance.

His season started spectacularly, as he led the Bengals to a 3–0 record. However, in game three versus Kansas City, Cook felt a pop in his right (throwing) shoulder after being tackled by linebacker Jim Lynch and missed the next three games. Possibly due to the limited medical technology at the time, his torn rotator cuff went undiagnosed. Despite this, Cook went on to pass for 1,854 yards and led the Bengals to wins over the Chiefs and the Oakland Raiders, two of the three best teams in the AFL. His 9.411 yards per pass attempt and 17.5 yard per completion are rookie records that still stand. Cook was UPI's choice for AFL Rookie of the year. Cook recalled, "I took cortisone shots and played in pain, but the shoulder hadn't started to deteriorate yet, so I could still function. I still had the strength. I felt obligated
