The side issue to Sunday's game between the Cowboys and Saints was the presence of defensive coordinator Rob Ryan on the Saints sideline.
He was fired by Cowboys owner Jerry Jones following a 2012 season when Ryan's defense set a team record for yards allowed.
Of course, Ryan was setback by a plethora of injuries on defense that was without five starters by the end of the season. The Cowboys hired Monte Kiffin to replace him because they felt his scheme's were simpler and more fundamentally sound than Ryan's.
Kiffin's defense has also been beset by injuries in 2013. The Cowboys were without four starters against the Saints and lost leading tackler Sean Lee during the game.
Kiffin's defense is on pace to not only set the team record for yards allowed, topping Ryan's unit, but be one of the worst in NFL history.
The contrast was in full and living color Sunday night as Ryan's Saints defense, which has been one of the best in the league all season, was dominant in holding the Cowboys to 193 yards, the fewest since 2008.
The Saints simply had their way with Kiffin's defense, amassing 625 yards. The most ever given up by the Cowboys and most given up in the NFL since 1982.
It all has Jones looking at his team and his decision with wide eyes and a hint of regret.
"We thought it was best for us to go in the direction that we are, and it doesn't look good right now," Jones said. "Hopefully we can make it look good, but I have all the feelings that you have when you want to look back at a decision, and I realize when some of them work you have to have a few things go along with it.
"Candidly, we're having some of the same things that Rob had last year. Frankly, to be fair to Rob, he lost a lot of guys on defense. We lost more this year. That's the game, though. That's what we play. That's the NFL."
