Marshawn Lynch's future among Seahawks' offseason questions

The Seattle Seahawks' season ended with a 31-24 loss to the Carolina Panthers in an NFC divisional-round playoff game. Here are five questions facing the Seahawks this offseason:

Has Marshawn Lynch played his final game with the team? There were questions last offseason about whether Lynch would return. Ultimately he decided to come back, but he played in only seven regular-season games. Lynch underwent abdomen surgery on Nov. 25 and returned Sunday against the Panthers. He had six carries for 20 yards. Lynch carries a cap hit of $11.5 million next season and turns 30 in April. Rookie running back Thomas Rawls was tremendous all season, carrying 147 times for 830 yards (5.65 yards per carry) before suffering a broken ankle. Assuming the team is confident that Rawls can rehab from that injury, Lynch's career in Seattle could be over.

Which free agents will the Seahawks attempt to re-sign? Two starters on the offensive line -- left tackle Russell Okung and right guard J.R. Sweezy -- are scheduled to become unrestricted free agents. The same goes for veteran wide receiver Jermaine Kearse. On defense, three of the starters in the front seven -- defensive tackles Brandon Mebane and Ahtyba Rubin, along with linebacker/defensive end Bruce Irvin -- are also no longer under contract. The Seahawks still have the core of their roster in place and will be contenders next season, but they'll face decisions on these six starters.

Will any players be unhappy with their contracts? Strong safety Kam Chancellor took his holdout into the regular season, missing the first two games. Defensive end Michael Bennett was also unhappy with his contract, but he showed up and turned in an outstanding season with 10 sacks and 18 tackles for loss. Both players are signed through 2017 on their current deals. Will the Seahawks' front office do anything for Chancellor or Bennett? And if the answer is no, how will they handle their dissatisfaction?

What does the future hold for Jimmy Graham? ESPN's Stephania Bell wrote an insightful post last month about Graham's difficult road to recovery from a ruptured patellar tendon, which is not an easy injury to come back from. Graham had 48 catches for 605 yards and two touchdowns in 11 games with the Seahawks. The offense averaged 31.2 points per game in the final five regular-season games without Graham, showing it can be prolific even if the superstar tight end is not on the field. He carries a cap hit of $9 million in 2016, and none of that is guaranteed. Coach Pete Carroll has gone on record saying that Graham will be an important part of the team going forward, but it's possible that the Seahawks will decide the money they've allocated to him could be better used elsewhere.

What's the plan at right cornerback? Last offseason, the Seahawks let Byron Maxwell go and signed Cary Williams to a three-year deal. Williams started the first 10 games but then was benched and eventually released. The Seahawks went with DeShawn Shead and Jeremy Lane down the stretch. Shead is a restricted free agent, and Lane is unrestricted. Will the Seahawks go into 2016 with one of them as the presumed starter? Will they go the free-agency route again, knowing the risk? Or will they try to develop someone on the roster such as Tye Smith? For the second consecutive offseason, the Seahawks will have to figure out a plan for the cornerback spot opposite Richard Sherman.
