Now with the unexpected loss, Arizona might be able to take the next step with its coaching search.
As time goes by, the longer the Cards haven't named Ray Horton as their new head coach, the more likely it seems if they aren't quite sold on making their dynamic defensive coordinator their next leader.
The fact that the Cards have struggled on offense and at the quarterback position so badly the past two seasons might be the reason they are reluctant to hire a defensive-minded head coach.
That sentiment is also why the team has talked with Todd Haley, according to this tweet from the Pittsburgh Post-Gazzette's Ed Bouchette, and Jay Gruden, as detailed in this report from Darren Urban at AZCardinals.com.
Another factor might have been the Cards being underwhelmed by the rumored coordinators that Horton was planning on bringing in—Kirby Wilson for offense and Lou Spanos for defense—according to this tweet from Mike Juecki at XTRA 910 in Phoenix.
This article from Pro Football Talk's Mike Florio mentions that Horton is expecting to know his fate by Tuesday.
The general feeling at this point might be that Horton may not get a head coaching position this winter and the Cards might be able to hold on to him for another season, something that seemed unlikely even two weeks ago.
If the Cards feel they can realistically pair McCoy and Horton together for a season, that might be viewed as the best-case scenario for the team.
Ownership might have simply felt the risk of hiring Horton would have weakened the Cards on both sides of the ball next season.
They probably wanted to have newly promoted general manager Steve Keim make the final decision on the hire as well—especially after parting with former head coach Ken Whisenhunt and general manager Rod Graves.
Whatever the reason for the slow pace of the search, Arizona needed to make sure that it hires the right person without appearing to settle for its second or third choice.
With the Broncos' surprising elimination, now is the time for the Cardinals to make their move.
