I know. I wasn't questioning that. I'm talking about inconsistent playcalling. run, run, pass, run, run, pass, run, run, pass is consistent, and 67% runs, which is still a very run heavy offense. run, pass, run, run, run, run, run, run, pass, run, run, run, pass, run, pass, etc. is run heavy as well, but probably a lot less conducive to consistent play from your QB when he goes so long between throws and has no idea when the next one will come.
And before someone chirps in, no, I'm not saying playcalling should follow a specific pattern. But playcalling can certainly help/hurt the rhythm of the QB, whether it's a run-heavy or pass-heavy offense.
