Seattle's offensive line has been much maligned for just about all of Pete Carroll's tenure in Seattle. During that time, the angst over Seattle's blocking has been fair in some cases and less so in others. The combination of Pete Carroll's philosophy for downplaying the short passing game in favor of shot plays, an extreme avoidance of turnovers that leads to Russ holding the ball instead of forcing passes, and the standard inflation of sack numbers due to having a mobile quarterback, have led to fans feeling like the pass blocking is maybe worse than it really is.
And while the pass blocking has been up and down, the run blocking has been generally solid to good.
