After high school at St. Mark's High School in Wilmington, Delaware, Watson attended Temple University. In four seasons for the Owls, Watson caught 98 passes for 1,629 yards (5th in school history) and 7 touchdowns.

Pro career
Watson signed with the Denver Broncos as an undrafted free agent in 1979 and played his entire nine year NFL career for the team, appearing in 125 games. After recording only six receptions in each of his first two seasons, in 1981 Watson had 60 receptions for a career-best 1,244 yards and league-leading 13 TDs (including a 95-yard reception in game 6, the longest in the NFL that season and 3rd longest in franchise history). His 20.73 yards per catch remains a Broncos franchise record, and earned him a spot in the 1981 Pro Bowl. Watson had 555 receiving yards the 9-game strike-shortened season in 1982, hauled in 59 receptions for 1,133 yards in 1983 and a career-best 69 receptions for 1,170 in 1984. The 13-3 Broncos lost to Pittsburgh in the first round of the playoffs, but Watson had 11 receptions for a franchise record 177 yards. Watson started 31 of 32 games over the next two years, but saw his production fall to 915 yards, then 699. In the 1986 season, Watson assisted the team to a championship appearance in Super Bowl XXI, catching 2 passes for 54 yards in the game. After starting just one game in the 1987 season, Watson retired with career totals of 353 receptions for 6,112 yards and 36 touchdowns.
