I never said they weren't, but a lot more goes into these things than the O line. There are some scheme limitations for one. We use very little pre snap motion, only 10% of plays. There are whole areas of the field and route that we don't run often or at all. When was the last time you saw a simple slant or a pass play that wasn't a check down to Edmonds or Fitz that was designed to be short to intermediate middle? Our passing game is basically a big half donut with a hole in the middle. Which means the linebackers have very little coverage to worry about and can focus on the run. We don't use TE's barely at all in the passing game. Between the 3 of them they will play 100+ snaps and might have 3 targets on average total.
For all the plaudits Kliff gets for his "offensive mind" there are huge holes in his play book.
