The pair each played 23 Third Division games in the 1959–60 season. Hancock went on to keep goal 47 times in the 1960–61 campaign, fending off competition from both Poole and John Cooke.

Hancock played 50 games in the 1963–64 campaign, with Cooke deputising on two occasions. He made 22 appearances in the 1963–64 season, but faced pressure from new signing Reg Davies.

Hancock played just six league and cup games for Bill Nicholson's "Spurs" in 1969–70 and 1970–71. He worked as Pat Jennings's deputy whilst Barry Daines was still learning the game. He left White Hart Lane and moved on to Bury in July 1971. He played 35 Fourth Division games for the "Shakers" in 1971–72 and 1972–73 under the stewardship of Allan Brown and then Tom McAnearney.

Coaching career
After retiring as a player he returned to Port Vale in July 1975 as a part-time coach under the management of Roy Sproson. He moved on to Cheshire County League side Leek Town as a manager in 1978, later serving as club chairman. He also sat on the Leek and Moorland League management committee. He co-founded Port Vale's Ex-Players Association with former teammate John Poole.
Style of play
Former teammate Roy Sproson described him as: "strong in dealing with crosses, quick reactions and a fine kicker of the ball". He went on to describe a save in an FA Cup tie with Sunderland as one where " turned in mid-air and managed to push the ball round the post in what still rates as the most fantastic save I have seen to this day." He also had the ability to drop-kick the ball into the oppositionpenalty area.
