Isaac played 14 seasons with the St. Louis Rams before signing with the San Francisco 49ers to play two final seasons. During his 16 NFL seasons, Isaac was considered one of the best receivers in the National Football League. He was a world-class route-runner, very elusive and highly intelligent with great hands and a tremendous overall threat. He was the first of three second-round draft selections (33rd overall) by Rams in 1994 NFL Draft. When he retired, he was No. 2 on the NFL's all-time receiving yards list behind Jerry Rice and No. 5 on the NFL's all-time receptions list. He had more than 1,000 career receptions and more than 15,000 career receiving yards. His #80 jersey was retired by the Rams in 2010 and he will be eligible for the NFL Hall of Fame in 2015.
Bruce made one of most famous plays in illustrious history of Rams' football, catching 73-yard touchdown pass from QB Kurt Warner with under two minutes to play in the game to give Rams' 23-16 victory in Super Bowl XXXIV.

Reeves Memorial Award, given to club's MVP, one of four players (DE Jack Youngblood 1975-76, RB Eric Dickerson 1983-84, and RB Marshall Faulk 1999-01) in team history to be honored with the award in back-to-back seasons. Bruce also holds three Rams' single-season records, including most receiving yards (1,781), most receptions (119) and most consecutive 100-yard receiving games (six).
