"The deal is believed to include more than $10 million for Lynch in the 2015 season alone. Lynch currently is slated to make $5 million in 2015, the final year of what originally was a four-year, $31 million deal.
The Seahawks believe that Lynch, who has rushed for at least 1,200 yards in each of the past four seasons, has outplayed his contract, sources say. They want to reward him for his work.
