TEMPE, Ariz. -- They’re two of a kind.

Arizona Cardinals coach Bruce Arians and Buffalo Bills coach Rex Ryan are among the most unique coaches in the NFL. They both have big, larger-than-life, bombastic personalities. They interject humor -- and hit the punch line with the timing of a game-winning grand slam -- into their news conferences. They don’t care what other people think.

And they both love F-bombs. A lot.

“That’s who he is,” Bills linebacker Lorenzo Alexander said of Arians, for whom he played in Arizona in 2013 and 2014. “He is who he is. That’s just what he does.”

Arians' and Ryan’s talent at utilizing F-bombs in a variety of usages and scenarios was, coincidentally, captured by TV cameras this offseason. Arians’ favorite word was used widely on “All or Nothing,” the eight-part documentary series about the Cardinals’ 2015 season on Amazon Video. Ryan’s was aired on the team-produced documentary “Rex and Rob Reunited.”

But who curses more?

“Oh man, that’s hard,” said Cardinals running back Chris Johnson, who played for Ryan with the New York Jets in 2014. “Rex curses a lot more in the media but B.A. curses a lot as far as ... I’d hate to be a ref. He gets on refs a whole lot.

“They curse at different times. Rex is more in the media. B.A. more at the refs, stuff like that.”

While their seasons could be heading in opposite directions, with Arians’ Cardinals sitting at 1-1 after a blowout win over Tampa Bay and Ryan’s Bills at 0-2, their personalities do more than create flashy headlines and good sound bites. They help them relate to their respective locker rooms in ways their players admire and respect.

“He’s a lot like Rex,” Alexander said of Arians. “I always kind of compare those guys as far as them letting you know how they feel. A lot of times head coaches or people in management are real close to the vest.

“They’re very open. They have a good time with the media. Big personalities. As far as coaching, I think both of those guys do a great job.”

Johnson and Alexander are two of the three players currently in the NFL who have played for both Arians and Ryan as head coaches. Colts cornerback Antonio Cromartie is the third.

Going from Ryan’s locker room to Arians’ in 2015 wasn’t much of a transition for Johnson, but he’s noticed a few significant differences.

“They’re very similar,” Johnson said. “It’s just Rex tells a lot more jokes. He’s way more talkative, more 'jokeative,' all those types of things.

“Bruce, he’s a good guy. He’ll joke around and stuff, but he’s more, like, business-minded. Like, let’s get to work, let’s get to business, let’s work and all the joking is for after that. But Rex is always joking.”

Arians’ record since getting hired as a first-time head coach in 2013 is 35-15. Ryan’s record since getting his first head coaching job with the Jets in 2009 is 54-60.

Johnson said neither coach gets down on players for the sake of establishing their authority. The openness they operate with is one reason they endear themselves to players -- and they know that.

“I think guys like honesty,” Arians said. “If it’s brutal, it’s still honest. They like being coaches and Rex is a hell of a coach. He knows how to get his guys in position to be successful and he knows how to teach it. That’s all players want.”

Ryan believes Arians can relate to players for two reasons. He has the “pelts to show the kind of coach he is and the coaching acumen he has.” And Arians is real.

“He’s just himself,” Ryan said. “That’s what you have to be in this business. I think if you try to be somebody you’re not, that’s not going to be effective. But, clearly, Bruce has always been himself and I think that’s why it’s so effective.”

If Arians had a walk-up song, it would be Frank Sinatra’s “My Way.”

That’s how he’s approached his first head coaching job, which he received at 60 years old. But it would have to be replayed for Ryan, who has handled his two head coaching stints in the state of New York the same way.

Arians has a unique ability to compartmentalize his job, Alexander said. He’s the head coach at work, and that’s clearly understood, Alexander added. But outside of the office, Arians can be the “cool uncle.”

“When you’re out hanging out, you want a beer, hang out, chill, watch the game, talk ball, regular life, whatever,” Alexander said. “You don’t feel uncomfortable, so he’s real welcoming in that sense.”
