With the Ravens defense backed up at its 4-yard line on third down, defensive coordinator Greg Mattison decided to rush three players at Patriots quarterback Tom Brady.
That gave Brady the time to wait for Deion Branch to shake free of cornerback Lardarius Webb in the end zone and hit him for a touchdown, which cut the Ravens' fourth-quarter lead to 20-17.
Ravens coach John Harbaugh said there are a number of reasons behind how they rush quarterbacks, from the protection they're expecting to a change in tempo.
"We wanted to get double coverage on three of their receivers," Harbaugh said on his weekly radio show on WBAL. "We forced him to hold the ball. He didn't get the quick throw right on the goal line like he usually does. There were other times when it worked where they didn't score."
