Fred Dean began his pro career by signing as a free agent with the Miami Dolphins in 1977. He was released by the club prior to the start of the 1977 campaign and inked a deal with the Chicago Bears late in the season. He was on the Bears active roster for 4 games but did not see any game action. Dean was cut by the Bears in training camp the following year. He signed with the Washington Redskins in October of 1978 and suited up for 8 games. He appeared in 15 games for the club in 1979 and the first 12 games in 1980 before being sidelined by a knee injury. Dean missed the 1981 season due to a ruptured bicep but returned to the field for the team in 1982, where he was a member of the offensive line dubbed the "Hogs" and won a Super Bowl. In total, Dean played in 40 games with Washington.
Following the 1982 season, Dean became a free agent and was quoted in the press as saying that the Redskins did not offer him a contract he deemed good enough. He signed a superior deal with the USFL Tampa Bay Bandits late in the league's inaugural season that extended through 1985. Dean's USFL rights were owned by the Washington Federals due to his playing for the Redskins. To facilitate Dean's signing with the Bandits, the Federals traded his rights to Tampa Bay for the rights to running back Rickey Claitt and a 2nd round draft pick in the 1984 USFL Draft (Keith Kidd, 31st overall). Dean played in 4 games for the Bandits in 1983 and 12 in 1984 but does not appear to have played in 1985.
Dean wore this Speedline jersey during his tenure with the Bandits. It has three rather significant repairs and appears to have had some customization to the sleeve and jersey length. The numbers are screened on and Dean's name has been sewn to a nameplate and attached to the jersey.
