maybe they will pay him more
maybe he thinks they are closer to be contenders
maybe he prefers Hue Jackson
maybe he likes dressing up like an extra from Mad Max Beyond Thunderdome

And he also is the one who drafted Brandon Marshall. But, this concerns me as well, he is basically no different compared to Jerry Angelo. Hopefully, its only Plan B at best.

When he was GM:

2002: 9-7
2003: 10-6
2004: 10-6
2005: 13-3
2006: 9-7
2007: 7-9

Notable draft picks during his tenure:
Clinton Portis
Jay Cutler
Elvis Dumervil
Brandon Marshall
Tony Scheffler

Not to mention the history before then. From the wiki:

Sundquist joined the Broncos in 1993 as a scout as Player Personnel Assistant (1992-1994), Director of Scouting from 1995-2001 and then promoted to General Manager.

At the age of 33 Sundquist served as College Scouting Director and was in that role during the Broncos’ back-to-back Super Bowl wins in 1997 and 1998. He supervised pro and college scouting, and was responsible for salary cap and contract analysis. Sundquist was promoted to GM in 2002 by owner Pat Bowlen after being pursued by both the Chicago Bears and Atlanta Falcons organizations. He was also a finalist for the President position with the Seattle Seahawks in 2004. He started at GM with five consecutive winning seasons, a franchise record. Sundquist left the Broncos following a 7-9 record in 2007 Denver Broncos season.

Recruited athletes

During his tenure, Sundquist helped Denver land players such as John Lynch, Daniel Graham, Al Wilson, John Mobley, Brandon Marshall, Mike Anderson, Olandis Gary, Clinton Portis (WAS), Reggie Hayward (JAX), Trevor Pryce (BAL), Brian Griese (TB), Deltha O’Neal (NE), and Nick Harris (DET). Sundquist was known for being one of the more active GMs in player acquisition through drafting, signing free agents and trades. Under Sundquist, the Broncos became one of the league’s most active traders. His most notable move came just before the 2004 season, when he dealt star running back Clinton Portis to the Washington Redskins in exchange for cornerback Champ Bailey, another to obtain Dre Bly from the Detroit Lions, and a No. 2 draft pick that turned out to be Tatum Bell. He also engineered a 2006 draft-day deal with St. Louis allowing Denver to move from the No. 29 overall pick to No. 11, where they selected Vanderbilt quarterback Jay Cutler. As a result, Sundquist’s GM term was the start of a franchise-record five consecutive winning seasons.

Not too shabby, I’d say.
