The Cardinals already interviewed Ray Horton, their defensive coordinator, and reportedly have scheduled an interview with Pittsburgh Steelers offensive coordinator Todd Haley. The Chargers haven't conducted any interviews - at least any that were confirmed.
On Monday, the same day the Eagles fired Reid, the Cardinals (Ken Whisenhunt), Chargers (Norv Turner), and Chiefs (Romeo Crennel) also fired their coaches.
Reid met with the Chiefs, including chairman and CEO Clark Hunt, team president Mark Donovan, and general manager Scott Pioli at Philadelphia International Airport, where many of the issues that would involve Reid's hiring were hashed out.
Donovan worked with the Eagles from 2003 to '09 as their senior vice president of operations.
The Kansas City Star reported that former Eagles and Chiefs coach Dick Vermeil spoke with Reid this week and told him "there are no negatives" to taking the job.
There were reports that Pioli would be out if Reid came aboard and that former Eagles and Browns GM Tom Heckert would replace him. Pioli worked with Bill Belichick in New England, however, and Reid has close ties to the Patriots coach.
Reid has been lining up his next staff for days, if not weeks. Brad Childress or Pat Shurmur would be his likely offensive coordinator. Marty Mornhinweg, who is still employed by the Eagles, is not expected to follow Reid to his next stop.
The Chiefs haven't won a playoff game since 1993. Reid won 10 in 14 seasons with the Eagles. Since 2005, Kansas City has had four head coaches; Crennel was fired after a 2-14 season. The Chiefs have the No. 1 overall pick in April's draft.
Falcons special-teams coordinator Keith Armstrong has been the only other interview for the Chiefs. He would satisfy the NFL's Rooney Rule, which requires teams to interview minority candidates for top coaching jobs.
The Eagles quietly hope that Reid signs with a team this offseason. Reid is due $5 million in the remaining year of his contact. But under an offset clause, if Reid signs elsewhere, an NFL source said, the Eagles would have to make up only the difference between his new salary and the one he was slated to receive from the Birds.
Reid has not spoken publicly since Eagles owner Jeffrey Lurie fired him on Monday. The Eagles had set up a news conference for Reid that morning, but he decided at some point to not answer questions, a team source said.
