If the Seattle Seahawks want to lock up quarterback Russell Wilson before he hits free agency, they are going to have to pay through the nose.

At least according to NFL salary cap expert Joel Corry.

Corry thinks that if the Seahawks want to extend Wilson, their offer will have to start at $35 million a year.

For comparison's sake, Wilson is scheduled to make $17 million in 2019, so this hypothetical new offer would start with more than double of what Wilson is earning annually.

It's not like Wilson doesn't have the track record to demand that type of salary, either.

The 30-year-old is coming off a terrific 2018 campaign in which he threw for 3,448 yards, 35 touchdowns, and seven interceptions while completing 65.6 percent of his passes and registering a passer rating of 110.9 en route to his fifth Pro Bowl appearance.

Wilson, who played his collegiate football at both the University of Wisconsin and North Carolina State, was originally selected by the Seahawks in the third round (75th pick overall) of the 2012 NFL Draft.

He immediately became Seattle's starting signal-caller during his rookie season and made the Pro Bowl after throwing for 3,118 yards, 26 touchdowns, and 10 picks.

The following year, Wilson led the Seahawks to a Super Bowl title and made another trip to Honolulu after finishing with 3,357 yards, 26 touchdowns, and nine interceptions.

Wilson has only improved since then, throwing at least 34 touchdown passes in three of the last four seasons, including the 2017 campaign in which he led the NFL with 34 touchdown tosses.

He also led the league in passer rating back in 2015 with 110.1 mark.
