Perhaps the biggest being the gaping hole on the left side of the offensive line.
In case you were stuck in traffic or still at work, the collective gasp you heard at around 5:30 PT yesterday was the result of Russell Okung getting carted off after the Seahawks first series.
By the time we even knew what was going on, Tyler Polumbus had already been beaten many times, leaving Tarvaris Jackson to scramble for cover.
Maybe we've been brainwashed by Michael Lewis with the help of Sandra Bullock in the Blind Side. Maybe we were blessed to have Walter Jones anchor the Seahawks line for the most successful stretch in franchise history.
Either way, the shoes that Russell Okung is left to fill are large.
The fact that both of Okung's ankles have been hurt and continue to get hurt in a little over a year's time since coming to Seattle leaves serious doubts about his durability, especially as this latest injury came without anyone touching him.
Last year you could blame his contract holdout and perhaps this latest episode is everyone just being cautious following the Lockout. Fortunately the x-rays came back negative; nevertheless it's a bit scary.
I believe the Seahawks made a solid choice with the sixth pick in last year's draft and have little doubt that Okung has the skill and disposition to play the critical left tackle position. However, I wish his ankles weren't made of porcelain. Let's hope this isn't a continual occurrence during his career. We've already lost him for six games his rookie year, we really can't afford to lose him for too many more games during this season and beyond.
