After several weeks of speculation that they would do so, the Seahawks have agreed to a deal to sign veteran pass rusher Dante Fowler Jr., filling what was perceived to be the last remaining hole on their roster. The deal is for one year and up to $5 million, as first reported by ESPN and the NFL Network. A source confirmed the deal to The Seattle Times. Fowler, 31, had a visit with the Seahawks last month and general manager John Schneider said after the NFL draft that it was still an option that Fowler could sign after the Seahawks did not take an edge rusher in the NFL draft. Fowler, entering his 12 th  NFL season, was the third overall pick of the 2015 draft by Jacksonville and has 58.5 sacks in 10 NFL seasons and will help fill out the depth at the edge rushing position after the Seahawks lost Boye Mafe in free agency when he signed a three-year deal worth up to $60 million with the Cincinnati Bengals.…
