The Seattle Seahawks' first step in addressing their offensive line was to sign Luke Joeckel to a one-year, $8 million deal on the first day of free agency.

But it's their second move that could be the most significant.

Pro Bowl guard T.J. Lang has a visit scheduled to Seattle, and if the Seahawks sign him it would likely represent the largest financial commitment to an offensive lineman since Russell Wilson became the quarterback in 2012.

Seahawks general manager John Schneider was the Green Bay Packers director of football operations when the team drafted Lang in the fourth round in 2009. The eight-year veteran has started 94 games and has missed just five games in the past six seasons.

According to ESPN Packers reporter Rob Demovsky, Lang showed the toughness to play through injuries and proved to be Green Bay's most consistent offensive lineman. Set to turn 30 in September, this could be Lang's last shot at one more big contract.

Offensive linemen got paid handsomely on the first day of free agency. Guard Kevin Zeitler signed a five-year, $60 million deal with the Cleveland Browns. Ronald Leary inked a four-year, $35 million contract with the Denver Broncos. If the Seahawks want to sign Lang before he makes additional visits, they'll almost certainly have to pay at least that much.

But adding Lang would go a long way in stabilizing the Seahawks' offensive line. He could take over at one guard spot, allowing Germain Ifedi, Mark Glowinski and Rees Odhiambo to compete at the other spot. Along with Justin Britt at center, that would be a competitive group on the interior.

At tackle, the Seahawks would give themselves options. Ifedi, Joeckel, Garry Gilliam and George Fant could compete for two spots. And the group would be deeper than it's been in years, even before addressing the offensive line in the draft.

The Seahawks only had two starters -- cornerback DeShawn Shead and linebacker Mike Morgan -- enter free agency Thursday. This is a team that has its core in place with the championship window wide open.

Bolstering the offensive line was clearly the priority going into free agency. Adding Lang to the mix would be a low-risk move that addresses the Seahawks' biggest need and solidifies a Super Bowl-caliber roster.
