Hobart was drafted by the Jacksonville Bulls of the USFL and later traded to the Denver Gold. His CFL rights belong to Edmonton, but Hamilton obtained them in a trade for Ross Francis. Hobart had an excellent rookie season, despite a somewhat low pass completion percentage of 48.2%. He had 2522 yards passing and ran for another 928 yards which earned him both East All-Star honours and the runner-up as the Most Outstanding Player in the CFL. Hobart didn't match that succes in the next two years in Hamilton and was released after the 1988 season in which he didn't play. Ottawa signed Hobart as a free agent, and he saw limited action with the Rough Riders.
Hobart had one kickoff for 35 yards in 1986.
