The team's acquisition of Williams was announced by team owner Paul Allen via Twitter last Thursday, but the addition of Bronson comes as a mild surprise as the team heads into its three-day mandatory minicamp on Tuesday.
To make room on the roster, the team released second-year defensive end Kenneth Boatright and rookie quarterback Keith Price, a three-year starter at the University of Washington.
Williams, 33, is a six-time Pro Bowler and five-time first-team All-Pro since being picked No. 9 overall out of Oklahoma State by the Vikings in 2003, racking up 60 sacks in 171 career NFL starts. He played out the last season of a seven-year extension he signed with Minnesota prior to 2007. His one-year deal with Seattle is reportedly worth over $2 million.
He told the St. Paul Pioneer Press that he turned down a similar contract offer to stay in Minnesota in favor of joining the Super Bowl champs, and ESPN's Ben Goessling reported that Williams turned down slightly more money to play for the New England Patriots. Williams also reportedly met New York Giants this offseason and even considered retirement before agreeing to terms with the Seahawks.
Bronson, a 2008 graduate of Kentwood High School in Kent, played his first two seasons at Washington before transferring to Cheney before the 2011 season. He was a short-yardage specialist for the Eagles with his best season coming in 2012, when he rushed for 472 yards and 11 touchdowns on 132 carries. He attended the team's rookie minicamp in May.
With starting tailback Marshawn Lynch not expected to attend minicamp, Bronson will get the opportunity to take some practice snaps behind Robert Turbin, Christine Michael and Spencer Ware. He will join former UW and EWU teammate Andru Pulu with the Hawks.
Price went undrafted in May after passing for 8,921 yards and a program-record 75 touchdowns for the Huskies over three-plus years on Montlake. Despite his prolific college career, Price was always a longshot to make the Seahawks' roster with Russell Wilson, Tarvaris Jackson, Terrelle Pryor and B.J. Daniels already in the fold when he signed on May 10.
Boatright signed with the Hawks as an undrafted free agent out of Southern Illinois in 2013. He did not appear in any regular-season games with the team.
