Quarterback Russell Wilson of the Seattle Seahawks appears to be on the verge of a massive contract after playing in the Super Bowl twice in three seasons.

Seattle has been negotiating with Wilson, who made less than $700,000 last season but could be in line for a payday of $20 million a year.

The cap hit for 2015 could be only a few million — he’s still under contract in the final year of his rookie deal — but will vastly impact caps in future seasons.

According to ESPN.com, the Seahawks and their 26-year-old franchise quarterback are closing in on a contract extension. There has been speculation that the deal could be fully guaranteed, which would give Wilson financial security but possibly offer less overall money that nonguaranteed contracts contain.

Wilson has made the Pro Bowl in two of his first three years in the league and guided Seattle to its first Super Bowl title.

Wilson hasn’t missed a game during his three-year career, and has increased his passing yardage while lowering his interception totals each season.

In 2014, he passed for 3,475 yards and 20 touchdowns, with seven interceptions.

Seahawks reporter Terry Blount of ESPN.com, while appearing on 710 ESPN in Seattle on Friday, said that a deal between the Seahawks and Wilson is expected soon.

“From what I’ve been told they’re very close, they’re just trying to make sure every single thing is in place before they go forward with this,” Blount said.

“I think it’s going to be bigger and crazier and different from what any contract has ever been.”
