receptions from 1967 to 1976, since surpassed by many players. Following the retirement of Charley Taylor, Biletnikoff spent the 1978 season (his last) as the NFL's active leader in career receiving yards, and retired ranked 5th all-time. Biletnikoff popularized the use of Stickum, an adhesive that many players applied to their hands to assist with catching and gripping the ball. He would apply the substance all over his body and uniform prior to a game, a practice that was later picked up by Raiders cornerback Lester Hayes after Biletnikoff introduced him to it. The use of Stickum was banned by the NFL in 1981. In his rookie season, Biletnikoff played primarily on special teams. He did not see playing time on offense until the seventh game of the year, against the Boston Patriots, in which he caught seven passes for 118 yards. His production increased significantly with Oakland's acquisition of quarterback Daryle Lamonica in 1967. That year, he caught 40 passes for 876 yards and five touchdowns and led the league with an average of 21.9 yards per reception. He was invited to play in the 1967 AFL All-Star Game. In that year's AFL championship game, Biletnikoff had two receptions for 19 yards in the Raiders' 40–7 blow-out win over the Houston Oilers. In Super Bowl II against the Green Bay Packers, he caught two passes for 10 yards as the Raiders were defeated 33–14. Biletnikoff recorded his only 1,000-yard receiving season in 1968, when he caught 61 passes for 1,037 yards and six touchdowns. The following season, in 1969 he caught a career-high 12 receiving touchdowns. He was an AFL All-Star for the second time and earned first-team All-AFL honors from the Associated Press, the Newspaper Enterprise Association, Pro Football Writers of America, The Sporting News, Pro Football Weekly, and the New York Daily News. The AFL merged into the National Football League in 1970. In his first five seasons in the NFL, Biletnikoff was invited to four Pro Bowls. A highly productive receiver in the postseason, Biletnikoff left the NFL as the all-time leader in postseason receptions (70), receiving yards (1,167), and receiving touchdowns (10) accumulated over 19 postseason games. He recorded over 100 receiving yards in a postseason five times. In the 1968 American Football League playoffs, he had 14 receptions for 370 yards and four touchdowns through two games. In the 1976–77 NFL playoffs, Biletnikoff recorded
