[1] DuBose began his professional career in 1977 with the Tampa Bay Rowdies of the North American Soccer League.
[4] He then found his way back to the Rowdies, who were also operating as an independent club playing exhibition games and invitational tournaments.
At the end of the season, he moved to England where he spent several months with the Second Division, now Championship, Oldham Athletic.
He was unable to get a work permit again until 1988, when he moved to Oldham Athletic at the behest of then-manager Rodney Marsh, with whom he had played in Tampa Bay.
"[8] When DuBose was trying his hand at European soccer in 1989, he was one of only a handful of American pioneers then playing professionally on the continent: only Chris Sullivan (Le Touquet AC), Frank Klopas (AEK Athens), Paul Caligiuri (Meppen), Bruce Murray (FC Lucerne), and Peter Vermes (Raba Eto) were also eking out a living there at the time.
He cites playing against Mexico in front of over 100,000 people at the Azteca as his greatest footballing memory, though the U.S. lost the match, 5–1.
He also worked part-time as a commentator for home games of the Tampa Bay Mutiny of Major League Soccer until the team's closure after the 2001 season.
As recently as 2010, DuBose served as the color radio analyst for the Tampa Bay Rowdies of the new NASL.
[10] He has coached and mentored youth teams for over 20 years, currently developing the next generation of U.S. keepers at FC Tampa Rangers.
