Rex Ryan jokes that Dan Campbell is one head coach he wouldn't fight

DAVIE, Fla. -- There are plenty of interesting ties in Sunday’s game between the Buffalo Bills (3-4) and Miami Dolphins (3-4). Among the obvious are Buffalo tight end Charles Clay and guard Richie Incognito, who two years ago was suspended for his role in Miami's bullying scandal.

However, Bills coach Rex Ryan dropped an interesting and little-known nugget Wednesday during his conference call with the Miami media. According to Ryan, he once tried to hire Dan Campbell on his coaching staff with the New York Jets.

They will face off for the first time as head coaches on Sunday.

"People that know Campbell has obviously been extremely impressed with him," Ryan said. "When I see his team, I get it. I see they’re going more two tight-end personnel, pounding the ball in there."

Ryan also joked about Campbell’s imposing, intimidating look. He is the youngest coach (39) in the NFL and a former tight end for a decade.

"Most times when I go across field I can whip most head coaches, but I ain’t whipping that one," Ryan said laughing. "I’m not even trying to whip that one. He’s a big dude, man. I’m 52 years old. I’d like to see 53."

Here are some other Dolphins notes from Wednesday's practice:

  • The defense wore the black alternate practice jerseys. That means Miami’s defense beat the offense in Monday’s practice. Players get a kick out of the new jerseys, and it’s another way for Campbell to promote competition in practice. The defense also won Wednesday’s practice, according to Campbell.

  • Chris McCain is making a full-time switch from outside linebacker to defensive end this week. The move was decided by the coaching staff after Pro Bowl defensive end Cameron Wake was put on season-ending injured reserve after tearing his Achilles. McCain has been a "tweener" getting work at both positions, but will commit to defensive end full-time. "It was kind of expected," McCain said. "I haven’t been in the linebacker room since Week 2."

  • Campbell said he hasn’t made a decision yet on rookie running back Jay Ajayi. Miami has the option to activate Ajayi, who has been out with a rib injury, for Sunday’s game or next week's game against the Philadelphia Eagles.
