My initial response is that I don't know enough about O-Line coaching to say either way - but if Campen's responsible for the play of that unit, I'd say firing isn't enough - he ought to be shot.
(That was hyperbole - I don't want the man to be shot.)
So, no - I'm not at all sure we should keep him. And I'm a little pissed that he managed to escape the reaper last year when we were culling the coaching ranks. O-Line still sucks, as of week 2.
I have no idea who we would replace him with, but I'm still pissed off enough about yesterday's game to want some blood.
