After that, Bowlen and his team of advisers could move quickly to offer the job to one of the seven hopefuls or start a second wave of interviews.
Among the more intriguing possibilities for further courting is Oklahoma coach Bob Stoops, whose second-ranked Sooners face No. 1 Florida in the BCS championship Thursday night.
Bowlen stunned the NFL with his firing last week of Shanahan, one of only six coaches in league history to win back-to-back Super Bowls -- and the only one to later get fired by the team he led to those titles.
Frazier's credentials might be just what Bowlen is looking for. He's coached a dominant unit in Minnesota the past two years, when the Vikings led the league in rushing defense by allowing just 74.1 yards a game in 2007 and 76.9 yards last season.
The Broncos' run defense has been porous ever since Larry Coyer was fired as defensive coordinator after the 2006 season and replaced by Jim Bates, who lasted less than a year before being supplanted by Bob Slowik.
The Broncos, however, suffered a rash of injuries, including ones that sidelined co-captains Champ Bailey and D.J. Williams. They spent the first month and a half experimenting with a 3-4 look and tried out six different free safeties. The result was a measly 13 takeaways and an NFL-high 448 points allowed.
Shanahan was 146-91 with the Broncos, but just 24-24 since losing the 2005 AFC title game to Pittsburgh. The three-year stretch without making the playoffs is the proud franchise's longest drought in 26 years, and this year the Broncos became the first team to blow a three-game division lead with three weeks left.
Forty-eight hours after the season ended at 8-8, Bowlen summoned Shanahan into his office to fire his close friend, who had three years and $21 million left on his contract.
For years, Bowlen had said Shanahan could coach his team as long as he wanted, but he finally grew tired of somebody else running his franchise and decided to split those duties. So, Bowlen said he'll start searching for a general manager after he hires a coach.
Shanahan has said he'll probably sit out the upcoming season before returning to coaching. He'll collect his $7 million salary from the Broncos while watching somebody else fix Denver's dreadful defense and fine-tune a promising offense that was his hallmark.
