There are two versions of Tom Brady: the dominant, record-smashing Tom Brady and the Tom Brady that plays against the Baltimore Ravens.
They are two very different people.
The Ravens have defended Brady better than almost any team in the league since he began tormenting defenses in 2001.
In those years, the Ravens and Patriots have met five times. While the Patriots are 4-1, they've never scored more than 27 points and won three of those contests by less than touchdown.
Brady has averaged 247 passing yards in those contests, never passing for 300 yards or more against the Baltimore defense. Even more incredible, Tom Terrific has thrown the same number of interceptions (six) in those games as touchdowns.
And although it would be pointless to dig up old history for most teams, the Ravens have had such incredible defensive continuity over the years that many of the same players that limited Brady in 2010, 2009 and 2007 will be on the field come Sunday.
With that as the wind in his sails, Joe Flacco will have ample opportunity to settle into the game and pick his chances to strike.
Against most defenses, Brady scores at such a relentless pace that opposing offenses feel pressure to score on every possession, taking out-of-character risks.
That hasn't been the case against this Ravens defense and their presence gives Flacco a chance to manage this game at his speed.
