100% right.
Peyton Manning doesn't get sacked. PERIOD.
But the Ravens played them very close back in November. Personally, as a biased fan, they should have won that game. They picked off Manning twice in that game and missed a field goal. They only lost by 2 points.
Ed Reed has a knack for making plays on Manning. The Ravens will be using a lot of 3 man front with the middle LB's blitzing on the inside. That's how they got to Brady.
It's not always about the sacks. QB pressures are almost just as important because you can force incomplete passes and possibly turnovers. Manning doesn't have the best playoff record among active QB's in the NFL.
