Let me express one concern regarding this back to the 80s football that we are discussing: Salary Cap.
It is generally accepted that it takes more good players to run the football consistently than to pass it. You need a good OL, good TE, good QB and at least one good WR to keep teams honest and of course a of very good RB. In the NFL where defensive players have great range, you pretty much need to successfully block 8 or 9 guys on all running plays for them to work so they are hard- especially out of the tight formations that you are talking about.
So how can you possible keep a team with enough good players to make this kind of football work in the salary cap era? You still need a strong defense, right?
