And Frank Reich knows the Buffalo Bills, after spending 10-years as a backup quarterback with the team.

The architect of the greatest comeback in NFL history says both of the men the Bills have interviewed for their head coaching vacancy in Arizona this week would make good head coaches for the team.

Appearing on The John Murphy Show Thursday night, Reich said former Arizona Head Coach Ken Whisenhunt would make a great Head Coach in Buffalo.

“I know Buffalo,” Reich said on the radio show.   “I know ‘Whis.’   I just think it’s a good fit for him.  He’s got the track record to back it up.  I know he had struggles, but every coach has struggles in this league.  I’d be excited.  I hope he gets it.”

“There are not a lot of coaches that have been real successful in Arizona,” added Reich.  “‘Whis’ took a team to the Super Bowl there –that says a lot.  He’s from Pittsburgh, so there are a lot of things about his candidacy, if I can call it that, that make him a real strong candidate.”

Reich spent last year as the wide receivers coach for the Arizona Cardinals.  He was dismissed by the Cardinals Monday, along with Whisenhunt and the rest of Arizona’s offensive staff.  But he says if Whisenhunt winds up as the Head Coach in Buffalo, he’d like to tag along.

“Obviously, I think I have a good relationship with ‘Whis,’ and I would be knocking on his door if he got the job, saying, ‘bring me along with you, I would love to go back to Buffalo.,” Reich told John Murphy.

Reich also had positive words for Arizona’s current Defensive Coordinator Ray Horton, who interviewed for the Bills Head Coaching vacancy earlier this week.

“There’s something about Ray. He’s got a great demeanor,” Reich said.  “He’s kind of a laid back guy, but you know he means business.   He’s done a phenomenal job with our defense.  I think he’s got a great feel for players.  I definitely think he’s a head coaching personality kind of a guy.  I think he deserves a shot.”

Reich is watching the Buffalo situation closely, as he gets ready for his next job as an assistant coach in the NFL.  After ten succesful years as Jim Kelly’s backup with the Bills, he’s already thinking about possibly coming back to the franchise.

“It would be kinda fun,” he said.  “Once I got into coaching, I’ve always told Linda (his wife), ‘I don’t know the future, but it seems inevitable we’re going to wind up back in Buffalo.’    Who knows?  I’ve stopped listening to all this stuff because you just don’t know anything right now; I don’t think anybody’s going to let any secrets out.  You just gotta sit tight and wait until Russ Brandon makes his decision.”

The John Murphy Show airs weeknights from 7-9pm on the flagship station of the Bills, WGR Sports Radio 550.

According to the AP, Kelly will interview with the Bills on Friday, a day after the Fiesta Bowl in Arizona. Kelly is considered on of the hotter NFL coaching candidates in the college ranks.

Bills President and CEO Russ Brandon, GM Buddy Nix, Assistant GM Doug Whaley and Sr. VP of Football Administration Jim Overdorf have all been in Arizona since Tuesday interviewing potential coaching candidates. The search committee has already interviewed former Cardinals head coach Ken Whisenhunt and current Cardinals defensive coordinator Ray Horton.

Buffalo’s search committee is then expected to travel to Denver this weekend for a reported weekend interview with Denver offensive coordinator Mike McCoy. That report also came from the Associated Press.

Per LaCanfora’s report Bills President and CEO Russ Brandon, GM Buddy Nix, Assistant GM Doug Whaley and Sr. VP of Football Administration Jim Overdorf met with Whisenhunt. They’re reportedly scheduled to interview Cardinals defensive coordinator Ray Horton Wednesday.

Horton already interviewed for the Cardinals head coaching job today as he’s still under contract to Arizona.

It’s been also speculated that the Bills may catch up with Oregon head coach Chip Kelly as his team gets set to play in the Fiesta Bowl in Glendale, AZ on Jan. 3rd.
