Feel free to do your own research.
For Dallas, penalties, sacks and negative plays are the difference between a top-five offense and a bottom-10 unit.

That doesn't say what you think it says.
It says some penalties are drive killers. I agree. It specifically goes on to talk about holding penalties. It even goes through the stats.
On a clear drive teams score points 43% of the time. On a drive with any penalty that drops only a small amount to 39.6%. So all penalties are hardly drive killers.
Holding on 3rd and 2? Drive killer.
False start on 3rd and 6? Drive killer.
Holding on 2nd and 8? Probably a drive killer.
This from Fro in my opinion was not a drive killer. Maybe for this poor offense, not for any average offense.
