After retiring as a player, Tedford became a volunteer assistant coach at Fresno State (1987–1988) under his former coach Jim Sweeney. He then coached as an offensive assistant for the Calgary Stampeders in the CFL (1989–1991); returned to Fresno State as quarterback coach (1992); was promoted to offensive coordinator at Fresno State (1993–1997); and worked as offensive coordinator at the University of Oregon (1998–2001). During his time at Oregon, the Ducks notched a Pac-10-best record of 38–10 while finishing progressively better each year (8–4 in 1998, 9–3 in 1999, 10–2 in 2000 and 11–1 in 2001). While at Fresno State, he was instrumental in developing many players who went on to the NFL: QB Trent Dilfer (1992–1993), QB Billy Volek (1997), RB Ron Rivers (1993), RB Reggie Brown (1994–1995), RB Michael Pittman (1993–1997), and WR Charlie Jones (1993–1995). From 1998–2001 at Oregon he worked with future NFL talents such as: QB Akili Smith, QB A. J. Feeley, QB Joey Harrington, RB Reuben Droughns, RB Maurice Morris, RB Onterrio Smith, WR Tony Hartley, WR Keenan Howry, WR Samie Parker, TE Justin Peelle, and TE George Wrighster. California After previous Cal coach Tom Holmoe resigned from his post amid a 1–10 season in 2001, the worst in Cal's history up to that point (the Bears would later go 1–11 in 2013), then-athletic director Steve Gladstone hired Tedford to become Cal's 32nd head football coach. Tedford inherited a program that had not had a winning season since 1993 and had only won 29 games on the field since then, including only 18 wins in Pac-10 play. During his time at Cal, Tedford became known for his work ethic, often working late hours in his office and sleeping on an air mattress. In evidence of his turnaround of the Cal program, season ticket sales jumped from 16,200 in 2002 to 41,336 in 2007, setting new records each year from 2004 through 2007. In Tedford's first season (2002), he led the Golden Bears to a 7–5 record, their first winning football season since 1993, the nation's biggest turnaround of the year, and was named Pac-10 coach of the year. The Bears ended a 19-game losing streak to Washington and a seven-game losing streak to arch rival Stanford in the Big Game. Despite their resurgence, the Bears didn't go to a bowl due to NCAA sanctions for academic fraud that were handed down shortly before Tedford
