Didn't Whiz initially turn down a 2nd interview with us, only to change his mind. Maybe go back to McCarthy & offer him another opportunity to interview. Can't be too proud when you were lucky to be 3-13.
Other then Mitch I cant find a source that thius actually happened. I did find this.....
"
Events Leading Up to Whisenhunt's appointment. Whisenhunt was back for a second interview - which, as planned (but don't read anything into it) spanned Friday afternoon and Saturday. His strengths are said to be (a) fearless play calling, (b) the development and utilization of "slash" type players like Randle El and Kordell Stewart and (c) belief in a strong running game. Along with Russ Grimm, Whisehunt remains in contention for the Pittsburgh HC job; however their list of candidates is said to have broadened to include the Packer DC (Tomlin), former Dallas HC and Pittsburgh OC Chan Gailey and (wow!) Mike Sherman."

"Whisenhunt becomes the Cardinals' eighth coach since the franchise moved from St. Louis to Arizona in 1988. He was one of eight candidates interviewed for the job, but one of only two who got a second interview. The other was former Green Bay Packers coach Mike Sherman."

The Cardinals continued working through their short list of coaching candidates Thursday, interviewing former Packers coach Mike Sherman a second time and setting up a second interview with Steelers offensive coordinator Ken Whisenhunt for today."

But who knows maybe he turned a second interview down before actually accepting one? Only Whiz, MB, Graves and Mitch would be my guess.
