Fair points, KFBD.
On the establish the run point, that seems like a bit of cherry picking as well. Picking 5 teams that run a West Coast or spread offense, have enough offensive aerial firepower to establish a sizable lead early, and then play kill the clock in the 4th quarter, doesn't exactly prove that all teams have to come out of the gate slinging the ball all over the sandlot to be successful. An offense needs to stick with what they do best. If its banging the rock up the gut and mixing in the play action, ala the Pittsburgh Steelers, or some other system. Also, teams the would go significantly the other way, with a balanced or run oriented attack early in the game and then swing to heaving it nearly every offensive snap are, probably, more likely to be playing from behind and are at a disadvantage to the defense, further reducing their offensive success.
