I'm not saying by any means that Anae is an awesome OC, but our fan base wants an OC fired more quickly than about any where else. The only OCs we have ever had that were incredibly good were Doug Scovil and probably Holmgren. Norm Chow had his seasons, but also had many that left fans scratching their heads (and calling for his head).
As for the run game, we lost Jamal and did not have a great RB available. Hines did admirably until injured and Brown as well, but you will never have a strong run game, regardless of the OC, with the current stable of RBs we have. I have my frustrations with our offense, but can't really bring myself to through the run game issues at Anae entirely.
