Look at it from Coach/GM perspective.
They believe this IS a playoff team and contender (experience be damned). Now, is the OC operating at THAT level? From my couch...probably not. "Sometimes good enough" doesn't read like someone that is getting it done.

Basically, the guy needs to dislodge his cranium from his posterior. Remember when Seattle just needed the Def to step up (last month, lol) and they'd be golden? Now, it's the offense...this team is SO close to being whole.
