Pittsburghs scoring stats are skewed by a 45-7 victory over KC, a game in which they didn't turn it over.
Pittsburgh typically turns it over, they're a careless team, and when they do so they are very beatable (exhibit A: Raiders beat the Steelers. The Raiders. Those Raiders)
But yes, if Pittsburgh doesn't turn it over, a rarity, they are very strong.
The Saints scoring stats are skewed by a 35-22 drumming by Baltimore, a game in which we turned it over 5 times. The Saints typically don't turn the ball over, they are a smart careful team. But when they do, they are very beatable (reference: Ravens game).
But no, if the Saints don't turn it over, they are not easy to beat.
So in other words, the game will likely come down to how careful or careless the respective teams are.
Gee, that's novel.
(Saints are more likely to be careful and have few to no turnovers then Pittsburgh. Ergo the Saints should be favored.)
