Guaranteed contracts in the NFL? This is a battle for Richard Sherman

Stay in any union long enough, you’ll realize it’s often only as good as its ability to get members to go on strike.

Sure, unions can obtain decent benefits in “peace time” between work stoppages. But ultimately, the best deals are almost always negotiated with the threat of a hammer dropping if things don’t go the union’s way.

Which brings us to Seahawks cornerback Richard Sherman, looking more and more like a future head of the NFL Players’ Association when speaking about topics other than himself. Sherman recently stated that only by being willing to strike and lose money would football players match the guaranteed contracts of their MLB and NBA brethren.

Which is bang-on advice a younger generation of upcoming NFL players may be more willing than ever to heed.

It’s not about matching MLB and NBA average salaries, nearly impossible because bigger NFL rosters mean far more players must be paid.

As Sherman pointed out, average salaries mean little in the NFL. It’s the only major sport lacking guaranteed contracts of some type, meaning all that matters today is signing-bonus money.

So it’s improving “guaranteed” salary he’s after.

The other thing increasingly important to NFL players is health and safety, something Sherman also has been outspoken about. Combine that with nonguaranteed contracts, there’s a potential spark to ignite a labor powder keg.

Calvin Johnson, Jerod Mayo, Anthony Davis, D’Brickshaw Ferguson, Husain Abdullah, Jason Worilds and Chris Borland recently retired in their NFL primes, forgoing big money rather than subjecting their bodies to increased punishment and painkiller drugs to keep playing.

The current NFLPA regime has made health and safety more of a priority than during its 25 years under the late Gene Upshaw. Last year, I spoke extensively with DeMaurice Smith, who succeeded Upshaw as executive director in 2009, and he filled me in on various strategies employed in public and behind the scenes to wring out improved on-field safety conditions.

Former Seahawks offensive tackle Jerry Wunsch told me in April he’d received pregame Toradol injections, Vicodin and a wide range of anti-inflammatory drugs just to stay on the field. And Wunsch gladly took them — his body pummeled into a gradually deteriorating mess — because he needed the weekly money.

Wunsch signed a five-year, $13 million deal with Tampa Bay in 2001. But after collecting a $2.2 million signing bonus, he earned only his first-year base salary of $450,000 for that 2001 season plus a $300,000 roster bonus before being cut in 2002.

Sure, $3 million earned off a $13 million deal is still a lot. But Wunsch never landed another seven-figure yearly contract. With the Seahawks, he signed six-figure deals over the next three years, routinely got released in-season and had to re-sign for progressively less money.

He’d stay in games in which he was knocked “senseless” and reduced to vomiting in the huddle.

“It was all about getting that next week’s paycheck,” he told me. “I was literally on a week-to-week deal. They could cut me at any time.”

After his career ended at age 32, he suffered from memory loss and constant pain that made it difficult to hold full-time work. Getting your life’s earnings up front in your 20s sounds great, but try making it last a lifetime with myriad medical issues.

Without guaranteed contracts, teams allow players to be battered to a pulp with little financial ramifications beyond the current season. In baseball, if Felix Hernandez gets a hangnail, the Mariners are shutting him down rather than mess with a $25 million annual investment guaranteed for years to come.

Thus, NFL player safety is arguably better protected if teams have more invested in it.

Teams forced to guarantee more of a $100 million contract over five years would think twice about letting a player use painkillers to take the field hurt in Year 1.

Today’s NFL players already are retiring early. It’s hardly unreasonable to assume this upcoming football generation might decide bigger guarantees are worth fighting for over today’s signing-bonus allotment.

And if that happens, it could very well be Sherman leading them into battle, the likes of which the NFL has never known.
