Broncos to add Okung, put Clady on block (2:21)

With Russell Okung headed to the Denver Broncos, the Seattle Seahawks will have to quickly move to Plan B to find a left tackle.

Given that the top options on the free-agent market have found new teams, general manager John Schneider and coach Pete Carroll could be forced to get creative. Below are five potential options for replacing Okung.

Ryan Clady: With Okung set to start at left tackle for the Broncos, Clady becomes expendable. The 29-year-old has missed 30 games in the past three seasons. He was sidelined for all of 2015 with a torn ACL, but when healthy, he is one of the top left tackles in the game. Clady is a four-time Pro Bowler and is due $19.5 million over the next two seasons. This is all about health. If a team is confident that Clady can come back healthy, his contract is reasonable, and restructuring always is an option. Because the Broncos don't have a lot of leverage, trade compensation is unlikely to be significant. If the Broncos can't find a suitor, they could be forced to release Clady. Targeting him makes plenty of sense for the Seahawks.

Joe Thomas: This would be the "swing for the fences" move. Thomas comes with less risk than Clady, having started 144 straight games. He's on a reasonable contract and is a nine-time Pro Bowler. The Cleveland Browns were close to trading Thomas in November, and given that he's 31, perhaps they'd again consider parting with him for a nice package of draft picks and players. In terms of compensation, Thomas would command significantly more than Clady. But the Seahawks have not made a first-round pick since 2012, and as we've seen in the past with Jimmy Graham and Percy Harvin, they're willing to gamble on talent.

Garry Gilliam: If the Seahawks look to options on the current roster, Gilliam is the most likely to get a shot. He started 16 games at right tackle last season, and the coaches seem to like his potential. But moving Gilliam to left tackle would be risky. He didn't play offensive line until his final year of college, and even then only made four starts. He mostly watched during his rookie season, but won the starting right tackle job last summer. It was the first time in his career he was a full-time starter on the offensive line. Asking him to move to the left side seems risky, especially for a team that should be competing for a Super Bowl.

J'Marcus Webb: This is a long shot, but not an impossibility. The Seahawks signed Webb, and he has experience with 44 career starts under his belt. Last year with the Oakland Raiders, Webb played right guard (13 games) and right tackle (three games). He was a left tackle with the Chicago Bears in 2011 and 2012. Playing Webb on Russell Wilson's blind side would be far from ideal, but depending on what other options the Seahawks have available, this can't be ruled out.

Draft pick: Schneider has talked about how difficult it is to find pro-ready offensive linemen in the draft, and it's never wise to draft for need. But Carroll has a history of letting young players compete for playing time. If the Seahawks hold on to the No. 26 pick, they could look hard at a left tackle. ESPN's big board has five offensive tackles in the top 32. The top three are likely to be taken before the Seahawks pick, but the likes of Ohio State's Tyler Decker or Texas A&M's Germain Ifedi could make sense.
