Without heavy blitzing, perhaps. But they blitzed plenty.
That Ravens gave was heavily blitzed as well. Corey Graham blitzed on that key 3rd and 2 in the 1st quarter and stopped Ridley in the back field forcing the field goal. Then right before the half the Pats are on their famous 2 minute drive, Ravens blitz, Brady gets flustered and runs into the back of the ref lol. A couple plays later they blitz again, Brady is flushed out of the pocket and slides (and kicks a Ravens player - should have been a penalty). Brady had to get up, run back to the line, and by that time there was less than 5 seconds left and had to settle for a field goal. Not to mention the reason the Patriots were knocked out of that game was that crucial knockout/fumble by Ridley in the 4th quarter. That was an oucher.
But anyway. There's more than one way to skin a cat and more than one way to beat Brady. But let's not pretend that blitzing him hasn't worked. It has. Many times. Including in AFC Championship games and Super Bowls.
This too.
