Frank Reich Still the Problem?

[HoosierinFL]

This offense is clearly flawed and its pretty hard for us to know exactly why.

Is it Reich's system and scheme that of course we still have to rely on?

Was it bad coaching from Reich/Brady to teach this system to the offensive unit?

Is it bad coaching of the offensive line?

Or is it some combo of regression of veteran o-line players and poor choices for replacements at RG and LT?

I don't see the all 22, so is it poor play from the receivers not getting open?

Is it bad coaching of the receivers?

Is it bad quarterback play?

Is it more likely some combination of any/all of the above?
