Absolutely I can understand the early season criticism. I think too much of it was focused on Bevell -- Cable's O-line hammered the offense more than the play calling (which was arguably directly impacted by the terrible line). But it was understandable nonetheless with the team losing and people getting frustrated/concerned about a possible lost season.
What I don't get is the continued negativity around Bevell and the total unwillingness by some to give credit where it is due. The passing offense has been as good as any in the NFL since the bye week. The line is better, Wilson is playing brilliantly. The creative play design is on another level. You throw to the full back out of the backfield on one TD, then on your next red zone possession fake the same throw and go to a TE on a crossing route at the other side? It's stuff like that where you realise how frickin creative the Seahawks are compared to so many tired, predictable, boring offenses.
Seattle finished with the second best offense in the league per DVOA. That is a beautiful thing.
