Dawkins was born in New Jersey but by the time he was in high school, he lived in Sunnyvale, California, where he distinguished himself as a Wide Receiver at Cupertino's Homestead High School, earning a football scholarship to the University of California, Berkeley.
While at Cal, Dawkins used his speed and size (6 feet 4 inches, 215 pounds) to establish himself as one of the country's most dangerous deep threats. His first two seasons at California were unqualified successes for him personally, as well as his Golden Bear teammates. In 1990, California won their first Bowl Game since 1938, defeating Wyoming in the Copper Bowl. The following season, the Bears dominated nationally ranked Clemson in the Citrus Bowl, which earned them the 7th ranking in the CNN/USA Today poll, their highest finish since 1950. It also marked the first time in school history that California won bowl games in successive seasons.
The 1992 season, however, included a new coach. After transforming the California program from a laughingstock into a national power, coach Bruce Snyder left Berkeley for Arizona State and was replaced by Keith Gilbertson. Gilbertson's squad struggled to a 4-7 record in 1992 but Dawkins was one bright spot in an otherwise forgettable year. Dawkins was named a consensus All-American after the season in 1992, an honor which encouraged him to forgo his senior season and enter the NFL Draft.
He was selected in the first round of the 1993 NFL Draft by the Indianapolis Colts as the 16th overall pick and the second wide receiver chosen. In his third season with the Colts, Indianapolis won two playoff games before falling to the Pittsburgh Steelers in the AFC Championship game. He would play in two more playoff games in his career, but both were losses.
He enjoyed his finest personal year in 1999 when he caught 58 passes for 992 yards.
After one season in New Orleans, Dawkins signed as a free agent with the Seattle Seahawks. After two campaigns with Seattle, Dawkins spent his final year with the Jacksonville Jaguars. His career was clearly on the decline by that point, as he made only 20 catches with the Jaguars that season. Before the 2002 season, he signed with the Minnesota Vikings, however he got cut at the final cutdown and never played in the NFL again.
As of 2003, Dawkins was living in the Sacramento area pursuing a career in real estate.
