I play adjusting the offense first, then the Defense, then call run or pass or option to roll the QB out to pass. The quick snap idea I got from several others but it works in adjusting the running backs to run toward opening holes. You can also adjust your linebackers to fill gaps. I've had some real life like collisions with that style.

Note: I have offensive line gaps at least a half inch (some times an inch) a part. That translates to about a full base width. I also don't allow the d-line to line up in the gaps but I can angle them towards a gap. That way you have some real mano-a-mano battles on the line of scrimmage. Tweaking skills and proper use of the TTC bases come into play. It becomes more of a chess game within the game between the O and D lines. The spacing allows you to shoot a fullback through to take on a linebacker or have a linebacker darn near decapitate a ball carrier.

Real life like in my opinion. Still working on it though.

don, i like this your style. gonna go try that.

the quick snap stoppage is so good.

Play action......
 

the "I" or the offset would work as long as you have rules stating you have to call "run" or "Pass" before the snap. There are leagues that do not have that rule so it's a hard sell - unless your run game has been working well.
