Green's best season in Minnesota was in 1998, when the record-setting Vikings finished 15–1 and set the NFL record for most points in a season (since broken by the New England Patriots on December 29, 2007). However, they lost in the NFC Championship Game, 30-27 to the Atlanta Falcons. Despite compiling a record of 97–62 in the regular season, Green was unable to reach the Super Bowl.
He attended John Harris High School (now Harrisburg High School) in Harrisburg, and graduated cum laude with a BA in finance from The University of Iowa. According to Green, he was planning to be a high school teacher if his football career didn't pan out. In college he started as halfback in each of his three seasons with the Iowa Hawkeyes. Green played briefly for the British Columbia Lions of the Canadian Football League in 1971, then worked as an assistant coach at the University of Dayton, University of Iowa and Stanford University, initially under Bill Walsh.
In 1989, Green took the head coaching position at Stanford University, inheriting a team that had graduated 17 of its 21 starters from 1988. Green led the Cardinal from 1989-1991. During that time, his teams were 3-0 in the Big Game against the California Golden Bears. In 1990, his Stanford team defeated the #1 ranked Notre Dame Fighting Irish in South Bend, Indiana. His tenure culminated with an 8-3 record (Stanford's best in years). A loss to Washington in the opening game of the season was the deciding factor for the PAC-10 championship. The Cardinal made an appearance in the 1991 Aloha Bowl, where his team lost to Georgia Tech on a last-minute punt return.
Through his first six years with the team, Green never posted a losing record and the team failed to qualify for the playoffs only once. Initially, Green earned widespread praise for turning around a what had recently been a lackluster franchise. However, as the team's fan-base grew accustomed to regular season success, Green came under criticism for failing to advance the team deeper into the playoffs.
In 1996, two members of the Vikings' ownership board, Wheelock Whitney and Jane Dyer, reportedly contacted Lou Holtz, who was the coach of the Notre Dame Fighting Irish football team and former coach of the Minnesota Golden Gophers football team. They wanted to bring Holtz in to replace Green. Holtz abruptly announced his retirement in 1996, and rumors surrounded the reasons, one of which was the possible Vikings head coaching position.
In November 1997, Dennis published his autobiography No Room For Crybabies, But There's Always Room for Jello in which he responded to the criticism and perceived personal vendettas by Twin Cities sports writers Bob Sansevere, Dan Barreiro, and Patrick Reusse.He threatened to sue the team as his response to the Lou Holtz rumors.
The high point of Dennis' Vikings career was the 1998 season where the team lost only one regular season game and set the NFL record for the most points scored in a season and finally advancing deep into the playoffs. Green reached several milestones, including coaching the former highest-scoring team in NFL history (now succeeded by the 2007 Patriots) and becoming the first black head coach to come within a game of The Super Bowl, losing in overtime to the Falcons.
2001 brought uncharted territory for Green as Vikings' head coach, with a losing record for the first time in his decade with the team. The Vikings bought out Dennis Green's contract on January 4, 2002. Assistant coach Mike Tice led the team in their final regular season game against the Baltimore Ravens. Tice was eventually named the head coach of the Vikings.
The Bears are what we thought they were, they're what we thought they were. We played them in preaseason, who the hell takes a third game of the preseason like it's bullshit, Bullshit!? We played them in the third game, everybody played three quarters; the Bears are who we thought they were! And that's the way we took the damn field. Now if you wanna crown them, then crown their ass! But they are who we thought they were, and we let 'em off the hook!
This phrase is still used heavily in NFL media coverage today, often comically, to describe the obvious flaws of an opponent and the failure to capitalize on that knowledge. It has been ranked as one of the best quotes of the past fifty years. The following day, offensive coordinator Keith Rowen was fired and replaced with quarterbacks coach Mike Kruczek. Though Green later apologized for the outburst, and the Cardinals eventually would rally to finish the season 4-3 in their last seven games, (including a rare win over playoff-bound Seattle) many pundits felt that the circumstances of the Cardinals' collapse against the Super Bowl-bound Bears on national television, combined with Green's tirade, had sealed his fate with the Cardinals.
On January 1, 2007, the Arizona Cardinals fired Green, although he had a year left on his contract.
In August 2007, the Westwood One radio network announced that it had hired Green to serve as a color analyst on their Thursday night NFL broadcasts.
