Miller played college football for the Oregon Ducks and was selected by the Atlanta Falcons in the first round of the 1987 NFL draft with the 13th overall pick.

[3] He was considered a risky recruit for higher ranked college teams due to concerns about a knee injury he suffered in high school.

He threw four interceptions in both his debut against San Francisco and his next game against Detroit, although he did record his first touchdown pass in the former.

In the Divisional Round matchup against Washington, he went 17-of-32 for 178 yards with four interceptions as the Falcons lost 24-7 to the eventual Super Bowl champions.

[10] In 1999, Miller was recruited to serve in the quarterbacks room of the Denver Broncos, who had rookie Brian Griese and Bubby Brister after the retirement of John Elway in the offseason.

[11] A collision during a run-fake on Monday Night game against Oakland saw him suffer a concussion that convinced him that it was best to retire for good in January 2000.

[13] Before the 2019 season, Miller announced he would depart West Linn at year's end to join the Houston Roughnecks of the XFL as offensive coordinator.

[16] He never coached a game for the Lightning, however, as his former position at West Linn opened up a few weeks later and Miller returned to the Lions on July 8, 2020.
