Anyone that really understands football knows there's more to a play than the play call. Execution is much more important.
Example is on third down in ot, the play call was a slant. It was great but didn't work because the pass wasn't where it needed to be, or the execution failed.
Early in the game when people were bitching about a particular run, it wasn't the run call that was bad but Fred's missed cut back.
Another example is how the guy 3 seats down from me was bitching about no play calls to the middle of the field. It turns out there were open receivers in the middle of the field that Thad missed. Play calls are half the battle.
I'm just not a blame the play call guy. I think Hackett is doing well with the what he has had to work with and being 6 games in.
