The YPG stats should not be used as a measure of a team's defense, you win games by scoring points not by accumulating yards. The Pat's defense only allows about 21 points per game, which is around 14th or 15th in the league. They also get a lot of turnovers, with 23 interceptions and 11 fumble recoveries. Their secondary allowed 26 passing touchdowns to 23 interceptions, pretty good TD to INT ratio if you ask me. The Raven's offense only scores about 23 points per game and Joe Flacco isn't exactly a great quarterback, I expect him to struggle. The Ravens defense hasn't yet been challenged with a great passing attack like the Patriots have. My guess is that the Patriots offense with Brady throwing to Welker, Gronk, and Hernandez will be too much for the Ravens defense. I think the Patriots will win 34-24.
P.S. I don't want the Patriots to win, I love the Ravens(mostly because of Ray Lewis and Ed Reed) but I'm thinking that the Patriots will be too much for them to handle.
