"These fundamental truths are as old as the game. Sunday night, the Saints elected to sit on the pass in running situations and dare the Cowboys to run, even feeding them mathematical advantages to make it more desirable. And that was the challenge. Could the Cowboys make New Orleans bring that safety down by dominating the numerical advantage? If they could win that 9-on-7 with enough regularity early, New Orleans would have to adjust, and that is when you kill them with the pass downfield – where the explosive plays and touchdowns are found.
But if the Saints could win even while giving up numbers against the run, Dallas would be in for a very long night."- Bob Sturm
