Miami Dolphins receiver Brandon Marshall scoffed in September that broadcast analyst Sterling Sharpe had no right to judge him. Marshall claimed Sharpe didn't do enough on the field to earn the privilege.
Imagine, then, how much disdain Marshall would harbor for criticism from those who didn't play in the NFL at all.
When you consider Marshall's logic and the sort of position coaches he has worked with, you get a sense of how unstable a situation can be.
As a rookie, he learned from former Pro Bowl receiver Steve Watson. But since 2007, Marshall's coaches have been Jeremy Bates, Jedd Fish and Adam Gase with Denver and Karl Dorrell last year with Miami. None of them played in the NFL. Neither Fisch nor Gase played in college.
Probably not the kinds of guys you'd expect to make a connection.
Dolphins head coach Tony Sparano rearranged his coaching staff after last season. He moved Dorrell into the quarterbacks vacancy and promoted Steve Bush from a quality-control role -- usually considered entry-level -- to receivers coach. Bush hasn't been an NFL position coach before. In 2008, the Dolphins hired the one-time Syracuse assistant away from West Genesee High in upstate New York.
Some help was in order, and not just for Bush.
Sparano made it a point to add former players to his coaching staff because he identified a deficiency. He needed more voices to reach his players.
Although the Dolphins parted ways with running backs coach James Saxon, they hired Ike Hilliard to assist Bush and Bryan Cox to coach pass rushing and promoted Dan Campbell from intern to tight ends coach.
"I feel good about the way we were able to put the staff together with the infusion of ex-players onto the staff," Sparano said last week at the NFL owners meeting in New Orleans.
"A little bit of that flavor and that knowledge on your coaching staff helps a lot. Sometimes, as coaches, we can get tunnel vision and forget about what the players' needs are. When you get an ex-player on your staff -- somebody that's really not far removed -- it helps you a lot."
A breakdown of AFC East coaching staffs shows there are multiple philosophies on former NFL players as assistants.
The Dolphins went into last season with two position coaches who played in the NFL: assistant head coach and secondary assistant Todd Bowles and Saxon. They now have four assistants with a combined 557 games.
Buffalo Bills head coach Chan Gailey has one former NFL player on his staff, but none coaching a position. Former defensive back Adrian White, a veteran of seven seasons, handles quality control.
New England Patriots defensive line coach Pepper Johnson is the lone member of Bill Belichick's crew to have experienced NFL action. Johnson played linebacker for four teams over 13 years.
Then there's Rex Ryan's staff, populated by six former NFL players with 62 seasons and 829 games. Matt Cavanaugh coaches quarterbacks, Anthony Lynn running backs, Henry Ellard receivers, Mike Devlin tight ends, Mark Carrier defensive line and Dennis Thurman defensive backs.
I reached out to three former coaches who played in the NFL -- Tom Flores, Herm Edwards and Ted Cottrell -- to get their opinions on the significance of having on-field experience on staff.
"It's always been a thing with the players," said Cottrell, an Atlanta Falcons linebacker and successful defensive coordinator for the Bills, Jets, Minnesota Vikings and San Diego Chargers, "where they think in the backs of their minds, 'Well, you haven't played this game. You don't know what we're going through. You haven't done this, Coach.' But if you have some playing experience on your staff, it helps offset that."
As valuable as those players-turned-coaches are, they're difficult to find. The best players don't necessarily make the best coaches because what came to them naturally can't always be conveyed through instruction.
Flores found a way to make it work. He and Mike Ditka are the only two in NFL history to win a Super Bowl ring as a player, assistant coach and head coach. Flores played quarterback for the Bills, Oakland Raiders and Kansas City Chiefs before guiding the Raiders to pair of Super Bowl titles.
"Some of the young kids coming out have no idea," Flores said. "They think they invented the game. Sometimes you have to bring them back to reality.
"But you also don't want somebody who keeps saying, 'Well, when I played ... When I played ... When I played ...' The player thinks, 'I don't give a damn when you played. We're playing now.'"
The transition from player to coach is difficult. Many players focus so much on their specific jobs when they're active that they don't become students of the overall game or learn how their roles fit into the overall puzzle. Others find it difficult to stop acting like a player when their careers are over.
Still, the ex-player element can be crucial in various instances.
"Sometimes you need a bridge with a former player," said Edwards, who played cornerback for the Philadelphia Eagles and was head coach for the Jets and Chiefs. "His voice is going to speak volumes, especially during the rough times because he's done it; he's been through it. He can give them, 'OK, this is what we gotta do' speech.
"He's going to respect because he played, but can he teach? That's the whole key. Players will figure that out."
Not all coaches are comfortable hiring former players, particularly those fresh off the field. Cottrell claimed there's a fear of subversion, that the former player will relate better to the locker room than the man in charge.
"Who do you think the players on the roster will gravitate towards more?" Cottrell asked. "The guy who played in the NFL and is young, or the older guy who didn't play?"
The former player, I responded.
"Damn right they would," Cottrell said. "That's why some coaches are intimidated to hire them. That's the truth. They don't want that guy around."
Added Edwards: "I've seen that happen. There's no doubt about that. That's when you're paranoid, but there are coaches like that."
Even so, Edwards conceded insurrections aren't an unfounded conspiracy theory.
"If you've got a former player in his positional meeting room, saying, 'Man, the coach doesn't know what he's talking about,' then you've got no shot as a head coach," Edwards said. "That's why you've got to be particular on who you hire."
The Patriots have a more institutional coaching staff. Their message is easy to deliver when players consider Belichick has won three Super Bowls and four conference championships in the past decade.
Rather than rely on former players, Belichick has core assistants such as offensive line coach Dante Scarnecchia (28th season with New England) and running backs coach Ivan Fears (15th season).
Belichick grooms assistants from gophers into coordinators and even head coaches. A steady stream of his acolytes -- Eric Mangini, Josh McDaniels, Brian Daboll, Bill O'Brien, Matt Patricia -- got their NFL starts under Belichick with no pro playing experience.
New England's cyclical process protects organizational doctrine from outside influences. Johnson, the lone ex-player on the staff, played 10 of his 13 seasons under Belichick.
"Belichick has a certain philosophy, and you want everybody to be on the same page," Flores said. "Sometimes, when you bring in guys that have been too many other places, they're not going to be on your page because they've been trained someplace else.
"If you bring up assistants through the ranks, then they'll be trained the way you want them to be. Everybody has to buy into the same program."
At the other end of the spectrum are the Jets.
Ryan obviously values former players. Their presence on the staff contributes to the Jets being an attractive destination for free agents, and Cottrell surmises the Dolphins have noticed.
"From a coaching standpoint, he looks at the Jets and wants to catch them in the division," Cottrell said. "He thinks, 'Rex has six guys that have played the game who are coaching. Uh oh. Rex has got an advantage on me.'
"That's got to be in the back of his mind. You've got to win your division to get into the playoffs, and when you look at your coaching staff, you see you don't matchup in that area."
Or, in the case of adding Hilliard at least, maybe it was as simple as noticing the Dolphins didn't match up with Marshall.
