Starting LT Russell Okung completed his free-agent odyssey around the NFL Thursday by agreeing to a reported, five-year, $53 million contract with the Super Bowl champion Denver Broncos. Okung, Seattle’s first-round pick in 2010, had also been courted by the New York Giants, Detroit Lions, Pittsburgh Steelers and San Francisco 49ers.

Multiple reports say that Okung’s first year is guaranteed at $5 million, with the remaining four years a the club’s option.

Okung is the second offensive line starter to exit Seattle during the current free-agency period, following RG J.R. Sweezy, who signed with the Tampa Bay Buccaneers March 9. Okung’s departure also means Seattle’s entire starting offensive line from Super Bowl XL (Okung, Sweezy, C Max Unger, LG James Carpenter and RT Breno Giacomini), a 43-8 thumping of the Broncos, is gone.

The Seahawks entered free agency with seven starters plus punter Jon Ryan up for grabs and have lost four. In addition to Okung and Sweezy, LB Bruce Irvin (5 years, $37 million) signed with Oakland and DT Brandon Mebane (3 years, $13.5 million) signed with San Diego. Seattle retained WR Jermaine Kearse, DT Ahytba Rubin, CB Jeremy Lane and Ryan.

The Seahawks selected Okung with the sixth pick in the 2010 draft out of Texas A&M. He made 72 appearances, all starts, and earned his only Pro Bowl invitation following the 2012 season.

Coming off shoulder surgery, Okung represented himself in negotiations (he consulted with NFL Players Association executive Mark Levin) and had sought a contract worth $12-13 million annually. Criticized for serving as his own agent, Okung explained his reasoning in a July, 2015 post for The Players Tribune, saying:

 I know my worth. I can look at the market and go directly to a team without an agent and tell that team my worth. And I can do so with confidence because I’ve done my research, I’ve educated myself and I’ve questioned the answers I’ve been given. And when it comes to reviewing the details of my next deal, I’ll hire an expert — a lawyer or a sports attorney who understands the dynamic of football contracts — to read the paperwork. I’ll negotiate a one-time flat fee that isn’t dependent on the size of my salary.”\

Also, according to Yahoo.com, Okung saved three percent, or $1.8 million, by representing himself, minus the flat fee.

Okung’s first contract with the Seahawks, a six-year deal worth a maximum of $48 million, guaranteed him $29 million.
