For me the key word is "time."
Whichever team wins the overall Time Machine battle at the line of scrimmage, wins the game.
Known variable: Experience.
Man About Town on Ragin Review accurately pointed out that experienced players just "do" inexperienced players have to take a split second to think. Advantage Louisiana.
Experience can accomplish the same thing a dominant line can. Just like a dominant OL can expand time for the offense and DL can shorten time for the opponent's offense.
Players who just do slow down the clock for themselves and speed up the clock for their opponent.
