I see a lot of things happening that are causing problems. I think a lot of this starts with the play calling, If most plays being called take so much time to develop, combined with an OL thats struggling - this obviously means your probably looking at a bad situation.
I would like to see him get rid of the ball sooner on many plays. Those little 5 yard passes are much more productive than losing 10 yards with a sack in hopes to make a huge play - HOWEVER this still requires the OL to buy him enough time to make a play.
I am not trying to cut these guys down, really I want to see them excell! The down to earth truth though is these issues lie with BOTH THE QB AND THE OL! Until these problems are resolved, we will be seeing a very compromised offense as opposed to what they should be.
