I will take the Saints offense over the Chargers offense any day of the weak.
Both have high power offenses, but the Saints depth at wide receiver [Marques Colston, Devery Henderson, Joe Horn] and running back [Reggie Bush, Deuce McAllister], plus Sean Payton's playbook is unreal in my eyes. Their vertical passing game is out of this world [Drew Brees on pace to get Dan Marino's record, currently 200 yards over Dan Marino in 13 games], and if they want to play smashmouth football, they have two above average running backs and a fullback that looked like the next Mike Alstott last Sunday night to do so.
New Orleans vs San Diego IMO, will be the best Super Bowl the world will witness in a long, long time.
