Re: ravens/ texans
One crucial key for an opposing QB to have success in "beating" Tom Brady is to have his defenses hold the Patriots offense to:
13 points (2007 Super Bowl)
17 points (2012 Super Bowl)
13 points (2013 AFC Championship).
That's how you "outplay" Tom Brady.
If I recall correctly, Matt Schaub helped guide the Houston Texans to 10 quick points before the half ended against the Pats, thus keeping the Texans in striking distance 13-17 at half-time!
I don't ever remember Eli Manning or Joe Flacco having to climb 13-24 or 13-31 deficits like Schaub had to try against Tom Brady!
