One thing you notice when looking at all 4 QB's that are left in the playoffs at this point is that their "weapons" change yet always somehow perform when they are behind Center.
It doesn't matter who Brady has as a supporting cast, the passing game soars.
It doesn't matter who Rodgers has as a supporting cast, the passing game soars.
It doesn't matter who Roethlisberger has as a supporting cast, the passing soars.
It doesn't matter who Ryan has as a supporting cast, the passing game soars.
You constantly see players coming out of nowhere and performing for these QB's while higher profile weapons flounder with lesser QB's. They also make their O-lines look better than they are, even after their O-lines have been hit by injuries and/or are apparently held back by such coaching liabilities as Paul Boudreau.
