The Seahawks' pass protection has dropped off dramatically this season. The team has allowed 41 QB sacks (plus one WR sack), up from 27 total sacks last season. The breakdowns appear to be across the board, from OT to OG to QB and RB. Remember, too, that a weaker run game forces the team into less favorable passing situations, which lead to more sacks.
In re-watching part of the second Arizona game recently, there was a second-quarter play in which DE Chike Okeafor beat LT Walter Jones around the corner, forcing Matt Hasselbeck to step up into the pocket. Instead of escaping, Hasselbeck ran right into Antonio Smith, who got credit for the sack. Smith had beaten RT Sean Locklear to the inside. You know things aren't going well when it's tough determining which player was most at fault for allowing a sack. There have been a few of those this season.
That aspect of the Seahawks' play absolutely, positively must improve against the Chargers today. Otherwise we could be looking at one of those six-sack games where Hasselbeck needs two ear-holes on each side to see what's going on.
