Huh? Why? Just getting the gang back together??

Mueller is essentially the expert on the professional side of scouting, I suppose. Never bad to have another set of eyes on talent scouting.

Likely signals the departure of Ireland for a GM role.

New Orleans Saints and ESPN
In 2000, Mueller became general manager of football operations for the New Orleans Saints. During his first year with the team, the Saints won the NFC West title and went on to win their first playoff game in franchise history. As a result, he was named Sporting News NFL Executive of the Year in 2000. The 2001 team could not improve, however, winning just seven games while selling only 25,000 season tickets for the following season to come, lowest in team history.

In 2002, Mueller traded running back Ricky Williams and the team's fourth-round selection in the 2002 NFL draft to the Miami Dolphins in exchange for their first- and fourth-round picks in 2002 and a conditional third-round pick in the 2003 NFL draft, which became a first-round pick after Williams ran for over 1,800 yards in his first season with the Dolphins. In May 2002, he was fired in what he called a surprise; owner Tom Benson called the firing one due to a "communication problem" in the decision process of making deals by management. He had been offered an extension on his contract (one year remaining) before the firing.[5][6][7]

From 2002 to 2005, Mueller served as an NFL analyst for ESPN.

Miami Dolphins
On June 6, 2005 Mueller was hired as the general manager for the Miami Dolphins. Because then head coach Nick Saban had the final say on all roster moves, unlike most NFL general managers Mueller did not have control over player personnel decisions. After Saban's departure in January 2007, Mueller's authority increased as he took over responsibility for player personnel decisions. Mueller was also heavily involved in the team's search for its next head coach and eventual hiring of San Diego Chargers offensive coordinator Cam Cameron. On June 26, 2007 Mueller signed a contract extension that was expected to keep him with the team as general manager through at least 2009.[8] Mueller was also to receive a salary adjustment, details of which were not publicly unavailable.[8] On December 31, 2007 ESPN.com reported that Bill Parcells had fired Mueller as the Dolphins finished 1-15 (Cameron was fired a few days later).[9]

San Diego/Los Angeles Chargers
Mueller joined the San Diego Chargers on April 29, 2008 as senior executive.[10]

Alternative football leagues
In 2018, Mueller was hired by the Salt Lake Stallions of the newly created Alliance of American Football (AAF).[11] After the AAF folded, he joined another fledgling league in the XFL, becoming the Houston Roughnecks' director of pro personnel in 2019[12] and later with the Seattle Dragons in 2022. On January 1, 2024, it was announced the Sea Dragons would not be a part of the UFL Merger.[13]

I'm on record as being against this move. It reeks of nepotism.
