In 1965 Maynard was teamed with rookie quarterback Joe Namath. Maynard had 1,218 yards on 68 receptions and 14 touchdowns in Namaths first season (Namath had 22 touchdown passes that year). In 1967, Maynard caught 1,434 of Namaths historic 4,007 passing yards. The receiving yards were a career-high for Maynard and led the league; he also had 71 receptions, 10 touchdowns, and averaged 20.2 yards per catch. In the 1968 season opener against 1968 Kansas City Chiefs season, Maynard had 200+ receiving yards for the first time in his career and passed Tommy McDonald (American football) as the active leader in receiving yards, where he remained for the next six seasons until his retirement. He added a career-best 228 yards in Game 10 against 1968 Oakland Raiders season. Maynard had 57 receptions for 1,297 yards (22.8 yards per catch) and 10 of Namaths 15 touchdowns that year. In the 1968 AFL Championship Game, a 27-23 Jets victory over the Oakland Raiders, Maynard caught six passes for 118 yards and two touchdowns. His 14-yard catch in the first quarter gave the Jets the lead and his six-yard catch in the fourth quarter proved to be the game winner. The Jets would go on to win Super Bowl III, 16-7 over the NFLs Baltimore Colts, which was hailed as the first "upset" in Super Bowl history. Maynard played, but had no catches while suffering the effects of a hamstring injury in the AFL title game.
