That is exactly what they did, no idea what this thread is about. The Patriots did not win all those SB's because they had an unstoppable offense. There are no offensive systems designed to get 3.33 yard per play or any that attempt to get 10 years at least one every three, that is just not at all how to think about it. A running play is not "designed" to gain 4 yards. You gameplan based on what you do well and what the opponent does not, you try to exploit matchups.
Do you have data to support this?
