NFL's pecking order

Rookie Will Davis said he hasn't experienced any acts of bullying or hazing.

"I think a lot of people think of hazing as being cruel, but I don't see anything like that in this locker room," he said. "But it depends on how you take hazing. I've always thought the guys in here were great."

He said everyone on the team loves Incognito.

"I was shocked," he said.

Wide receiver Mike Wallace said there was a lot of respect for both players.

"I know both of those guys personally," he said. "I feel like they are both good guys."

Former Dolphins linebacker Channing Crowder told "Piers Morgan Live" that a locker room is often a place where players are trying to establish a pecking order.

People cannot compare it to working at a regular job, he said, because we are talking about physically aggressive men with big egos competing and trying to prove their manhood.

NFL players are "a bunch of testosterone-filled alpha males who are trying to find their place on the totem pole," he told CNN.

He said when Incognito joined the team, he would test people to see where he stood with them.

"He is a guy that needs to know his place with you," Crowder said.

Incognito also apparently liked to play pranks. In a segment shown on a HBO series that follows one NFL team during each preseason, Incognito figured out a teammate's iPad password. He then teased the player about a status update he made for the player and joked about the player's fiancee.

"Hard Knocks" has given audiences a look inside team dynamics, sometimes giving viewers a glimpse at life for rookies. And inevitably some of the younger players get hazed.

Hazing on the decline?

Still, former Dolphins running back Ricky Williams said it occurs less frequently in the NFL than most people think.

"Really I haven't see much hazing," he said in an interview on "The Lead with Jake Tapper."

He said its a well-known "rite of passage" for a high draft pick to pick up a big dinner bill for some other players on the team.

"Once you sign that contract there's a lot of rules, written and unwritten, that you are expected to follow," he said. "For me, this is something that should be handled internally. I don't think the media, I don't think fans, I don't think anyone outside is really in a position to really fully understand what occurs inside of a locker room and inside of a football team."
