300+ yard rookie games in franchise history. He completed 41.5 percent of his passes, and averaged 7.1 yards per attempt and his 17.1 yards per completion led the American Football League (and ranks 18th all-time). He also ran for 308 yards and three touchdowns. Before the 1969 season started, Briscoe, still determined to play quarterback, discovered that head coach Saban intended to use Pete Liske as the starter, so he asked to be released. He went to the AFL's Buffalo Bills where he was turned into a receiver, since the Bills already had superstar Jack Kemp, former Pro Bowler Tom Flores, and James Harris, another black quarterback with a more prototypical 6-foot-4 and 210-pound frame. Briscoe led Buffalo in touchdown catches in each of his three seasons there and in receptions twice. In 1970, he was in the top two in receptions and receiving yards and became an All-Pro. After the AFL-NFL merger, Briscoe played in the National Football League from 1970 though 1976, mostly with American Football Conference teams. In 1971, the Bills traded him to the Miami Dolphins for the first-round draft pick used to take Joe Delamielleure, who developed as a Hall of Fame guard. Briscoe went on to win a pair of Super Bowls. Briscoe led the undefeated 1972 team with four touchdown receptions and was the leading receiver on the Dolphins in 1973, catching more passes than future Pro Football Hall of Famer, Paul Warfield. Briscoe made stops with the San Diego Chargers and Detroit Lions, before ending his career in 1976 with the New England Patriots; he had ten receptions for 136 yards and one touchdown in 14 regular season games for the Patriots in 1976. Briscoe caught a 16-yard touchdown pass from Steve Grogan in the Patriots 48–17 rout of the Oakland Raiders at Schaefer Stadium on October 3, 1976, which was the Raiders' sole loss that season. As a rookie, Briscoe was intercepted by Boston Patriots AFL All Star Defensive Back Leroy Mitchell in Denver's 35–14 rout of the Patriots at Fenway Park on November 3, 1968. He is the only player to have been intercepted by a Patriot player and later to have caught a touchdown as a Patriot receiver. Retirement and legacy Upon retirement from professional sports, Briscoe moved to Los Angeles. He became established as a successful financial broker, dealing in municipal bonds. Briscoe became addicted to cocaine, but
