Clearly the Seahawks are looking for a serious offensive line upgrade this offseason, both the Joeckel deal and the Lang offer demonstrate this. The best move at this point would be to find young OL talent with potential, rather than throw money at an aging veteran - like Clady or Evans. There are few (none?) starting caliber offensive linemen left in free agency, so a trade may be the best option.
Here are a few options, both free agents and trade targets. All are younger, and some have some untapped potential.
Brian Schwenke (G) - Drafted by the Titans in the 4th round out of Cal, Schwenke has experience at both Guard spots and Center. Has the athletic profile that the Seahawks prefer, but has very short 32" arms. Has some starting experience, and could be a solid back-up. Would likely only be on the roster to push the current starters - I do not see him beating out Glowinski, Britt, or Ifedi. His contract would have to be very reasonable to sign him
Austin Pasztor (G/T) - Interesting prospect. Has bounced around a bit. Was the 4th overall pick in the first round by Edmonton in the CFL, and was not drafted in the NFL. Can play both Guard and Tackle, and started some games for Jaguars. I do not believe he was a starter for the 1 1/2 years he was on the Browns active roster, but I could see Seattle being interested in his athletic profile and position flexibility. Again, would likely be a back-up.
Joe Dahl / Laken Tomlinson, Detroit - With the addition of TJ Lang, neither Dahl nor Tomlinson have a starting position on the Lions roster, and they also have Brandon Thomas - former 49ers 3rd round pick - signed to a futures contract. I think Dahl is the much better player, and fits the Seahawks interior line needs. But Tomlinson may be more readily available. I would not be surprised at all if Seattle was not already on the phone with Detroit to see about the availability of either of these two. I believe Dahl could challenge Glowinski for a starting spot day one.
Connor McGovern, Denver - Drafted in the 4th round in the 2016 Draft, McGovern was someone that I was very high on and hoping the Seahawks would select him. Currently a back-up with Denver, and they just dropped a bit of cash on the OL. They may consider moving McGovern for a draft pick. It would be perfect if we had our 4th rounder, and offer that to Denver. I would hope that they would consider a 2018 3rd rounder....would hate to spend one of the 2017 3rd rounders with the incredibly deep draft on defense.
Isaac Seumalo, Philadelphia - Another backup who may be available for the right price, Seumalo was drafted in the 3rd round last year. Not sure the Eagles would want to move him, and the cost would likely be more than we would be willing to pay. But he fits the athletic profile that the Seahawks typically look for in an interior OL.
Caleb Benenoch, Tampa Bay - Benenoch was a 5th round draft choice of the Bucs last year, and is another backup. He has ok athleticism, and was primarily an OT during his years at UCLA. He is currently a primary OG backup, and that is probably his long-term position. May be able to get him for a low round pick, but I do not think that Benenoch has the potential to be much more than a career backup. Likely a solid backup, but may not be much of an improvement over what we currently have starting. Potential is there though.
Any other names you would add to the list?
