The irony here is that this particular season the coaching has been solid on offense. Scheme is being put together that gives the offensive players OPPORTUNITY all over the joint. Every single game dudes have been open for big plays. For the first time in Fisher's run with this team I can say I'm actually OK with the offensive coaching this year.
But players matter too. Coaches can only do so much, and what we're seeing is the truth of that. Case is a backup level QB in this league and that means he's not going to thread the ball and make wow plays like a starter talent will. Less room for error, and it is made worse by mental lapses on too many of the wideouts.
Look at the defense... Williams will sit a dude quickly if he's not doing what he needs to. But offensively guys keep getting excuses and more playing time, and it's part of the reason IMO that Quick took so long to get it. Hold them accountable with bench time. Bench Robinson in-game if he's playing poorly, and let him feel that. They have the depth to move Saffold over and insert another OG. Bench Britt for a series if he's not running all out on routes he is a third read on. The team has other guys they can put in there.
