While I am concerned, I think it's a bit early to start blaming Shula just yet. It seems to me teh big difference between teh two teams yesterday can be summed up with one word: receivers.
The Seahawks receivers made some beautiful plays while ours either had untimely drops (Olsen) or just couldn't get open. Between the drops, personal fouls and fumble, we simply beat ourselves.
You simply cannot have those mental mistakes against any quality team and expect to win - regardless who the OC is.
