Russell Wilson and the Seattle Seahawks have agreed upon a four-year, $87.6 million contract extension.

Wilson's annual average ranks second in the NFL behind just Aaron Rodgers.

Wilson was scheduled to make $1.54 million this season, the fourth and final year of his rookie contract. The deal includes a $31 million signing bonus and approximately $60 million in guarantees.

"Blessed to be w/ this organization for 4 more years! Can't wait to get on field w/ the fellas!" wrote Wilson on Twitter.

There is pessimism that the Seattle Seahawks and Russell Wilson will reach agreement on an extension before their self-imposed deadline.

Wilson and the Seahawks have been in talks trying to get a deal done.

The gap between the two sides is based on cash up front and guaranteed money. Most of the significant guarantees in the current discussions are for injury only.

Wilson has stated several times he's willing to play out the final year of his rookie contract, which pays him a $1.54 million base salary.

Kam Chancellor wants more money in his deal and is threatening to hold out as the Seattle Seahawks begin training camp.

Chancellor has three seasons remaining on the deal he signed in 2013 and is scheduled to count $5.65 million against the salary cap.

The Seahawks redid Marshawn Lynch's contract last year to get him into camp.

ESPN has made some changes to their formula for total QBR, which has become a widely used metric to evaluate quarterbacks.

How interception returns, pressure and credit for yards after the catch are factored were changed.

Russell Wilson's QBR increased by 8.2 points, moving him from 12th to eighth in the rankings. Wilson was one of the top players in the NFL when under pressure.

Aaron Rodgers' QBR decreased by 5.2 points, but he remained ranked second. Rodgers' QBR decreased due to how the new formula handles yards after the catch.

The Seattle Seahawks and Bobby Wagner are making progress on a new contract.

The two sides opened up talks in June. Wagner is slated to earn just under $1 million in the final year of his rookie contract.

Wagner was a first-team All-Pro last season and has emerged as one of the NFL's best middle linebackers.

Russell Okung plans to negotiate his next contract without an agent.

Okung will be a free agent next offseason.

“I know my worth. I can look at the market and go directly to a team without an agent and tell that team my worth,” he said. “And I can do so with confidence because I’ve done my research, I’ve educated myself and I’ve questioned the answers I’ve been given. And when it comes to reviewing the details of my next deal, I’ll hire an expert — a lawyer or a sports attorney who understands the dynamic of football contracts — to read the paperwork. I’ll negotiate a one-time flat fee that isn’t dependent on the size of my salary.”

Okung will save himself the standard three percent commission an agent can receive.

Brandon Browner has interest in someday returning to the Seattle Seahawks.

The New Orleans Saints signed Browner to a three-year, $15 million deal in the offseason.

Browner was a part of the Seahawks' "Legion of Boom" defense during the Super Bowl-winning season of 2013. Browner played on another Super Bowl winner in 2014 with the New England Patriots.

Russell Wilson and the Seattle Seahawks will no longer discuss a contract extension once camp begins.

The two sides have been talking about an extension since the Super Bowl ended.

Wilson continues to be interested in a fully guaranteed contract as one of his negotiating points.

The Seahawks and Wilson are not close on a deal but talks are expected to ramp up.

Wilson is prepared for the possibility of playing 2015 on his base salary of $1.54 million. 

Russell Wilson continues to believe his contract standoff with the Seattle Seahawks will work out.

"I love Seattle, it's a great city," Wilson continued. "I'm going to play my butt off every day. That's all I know, and we'll see what happens."

Little has changed since June with Wilson's contract negotiations.

"Well, he's crucial, as are all of our guys, and we want him back playing for us forever," Carroll said. "There's a lot of work being done. It's underway right now and maybe it happens, I don't know. We're hoping for it."

Russell Wilson and the Seattle Seahawks continue to each take a hardline in their contract talks.

The Seahawks can use the exclusive franchise tag on him for 2016, which would give him an approximate contract worth $20 million.

Doing so again in 2017 would increase the figure to around $24 million.

If the Seahawks used the tag on him for a third season for 2018, it would likely rise to $34.6 million.
