Flacco isn't having a down year, he is having a typical Flacco year.
Just threw that in there because Sanchez gets a lot of heat and Flacco never seems to get any even though he is just as average as Sanchez.
I would lean toward Joe having a down year, but even if Flacco does suck, it doesnt make Sanchez suck any less, just makes Flacco over-hyped.
