After this season, the Seahawks figure to give a contract extension to Russell.

Wilson. Not Okung.

While the quarterback has far exceeded expectations over his first two and a quarter seasons, the left tackle has largely been underwhelming since being drafted sixth overall in 2010.

Both are signed through 2015, which means next offseason is the key time for extensions. Wilson will get his, but it’s hard to see Okung getting one — especially if he continues to struggle like he did Monday night.

The left tackle was flagged for three penalties vs. Washington, including a false start on third down that helped stop a first-quarter drive and a holding on a third-quarter drive that also fizzled.

“I’ve got to play better,” he told The Seattle Times. “I can’t afford to have three penalties. Just a lack of focus. I take full responsibility for it. I can’t help out the line making mistakes like that.”

Okung has not offered much consistent help since 2012, when he went to the Pro Bowl after giving up just two sacks and committing nine penalties in 15 games.

He missed half of last season with a toe injury that required surgery in the offseason, and he really hasn’t been the same guy since.

Coach Pete Carroll said Okung has expectedly been slow to come around after missing much of training camp, and he still is not completely healthy. In addition to the foot, he probably is still feeling the effects of a shoulder injury he suffered against Denver.

“He’s well enough to play,” Carroll said, adding that he hopes Okung “will continue to improve.”

Okung can make some great plays, no question — such as the block he made to help Marshawn Lynch score the winning touchdown in overtime against Denver.

But — largely due to the fact that he cannot stay healthy — he has been very inconsistent overall. He also commits far too many penalties — 11 in his last 12 games, including a false start on Seattle’s own goal line in that disastrous fourth quarter vs. Denver.

In the fifth year of his six-year rookie deal, Okung is making $8.76 million this season and counting $11.24 million against the salary cap (second on the team behind Percy Harvin’s $13.4 million). Having missed 19 games in his first four years and having played injured a lot beyond that, he just is not worth that outlay.

The Hawks seem very unlikely to want to pay him that kind of money in a new deal, especially when they will have to pay Wilson $20 million a year.

Okung’s salary actually drops to $4.8 million next year (barring any escalators), which could make it easy to trade him — if he stays healthy and plays well enough the rest of this season to attract interest. If the Hawks could get a second-rounder and perhaps another pick for him, it might be worth the move to save the money and move on to a cheaper, healthier option at left tackle.

The Hawks could draft a left tackle next year and let the rookie compete with Alvin Bailey and Garry Gilliam for the No. 1 spot.

In the meantime, the Hawks have to hope Okung gets healthy and starts playing with more focus, giving the other Russell some penalty-free protection.
