Jones was a record setting college quarterback at the University of California, Davis, where in two seasons as a starter he became the first UC Davis quarterback to pass for over 3,000 yards and over 50 touchdowns in a season, while leading the Aggies to a 17-2-1 record during his junior and senior seasons (1992–1993). In 2000, Jones was inducted into the UC Davis Aggies Hall of Fame. During these college years, he also focused on the Dramatic Arts. Notable roles include the part of Juan Perón in Evita, and of Vladimir, in Samuel Beckett's Waiting For Godot. Jones is married to another UC Davis alumnus, Justine. They have two daughters together, Jaelyn and Siena.
Jones joined the Arena Football League's Albany Firebirds in 1995. For the next two seasons, he received very little playing time, making only 3 out of 5 pass completions in his first season, and 3 out of 4 pass completions in 1996.
In 1997, Jones signed with the BC Lions. Jones played very little during his three-year tenure with the Lions, as he was relegated to the backup spot behind incumbent quarterback Damon Allen.
In 2000, Jones joined the Winnipeg Blue Bombers. Though he initially served as a backup to Kerwin Bell, Jones eventually won the starting job during the middle of the 2000 season, thereby clearing the way for the Bombers to release Bell in midseason.
Jones' following season (2002) was even better statistically, which included 5,353 passing yards and 46 touchdown passes. This was the third most passing touchdowns in a season (behind two seasons in which Doug Flutie completed 47 and 48)). From 2000 to 2002, Jones' 107 touchdown passes exceeded the record by any other quarterback in the CFL or NFL over the same period of time. In four seasons with Winnipeg, Jones set seventeen Bomber passing records, including throwing for five touchdowns in a game four times in one season.
Prior to the 2006 season Jones was signed by the Eskimos only to be released by them once more on June 10, 2006 as part of training camp cuts.
Three days later, on June 13, 2006, the CBC announced that Jones would be their sideline reporter for their CFL on CBC broadcasts.
On October 17, 2007, Jones inked a standard one-year contract plus an option with the Winnipeg Blue Bombers and then signed his retirement papers right after. The paperwork means Jones officially retires as a Bomber, the team he had the most success with during his four-team, nine-year CFL career.
