Analysts like Trent Dilfer and Peter King have already pegged this Super Bowl as almost a carbon copy matchup of Super Bowl XVLII, with most of the linemen from the New York Giants and New England Patriots returning to the big stage. While that is true, I think a few key additions made in that four year span will make a huge difference in how well Tom Brady is or isn't protected. This game-within-the-game will decide the Super Bowl.
While Michael Strahan had an illustrious career as a Giant that ended in Super Bowl XVLII, I think Jason Pierre-Paul poses a stronger threat as a pass rusher. He is able to use speed and leverage much more effectively than Strahan, whose power and technique allowed him to play effectively for over a decade. Also, Jason is a few inches taller and has a larger wingspan, which allows him to bat down passes at the line of scrimmage with greater ease. Add Jason's agility and quickness and it will be hard for New England to decide who to single-block when the Giants go to their NASCAR package of four defensive ends.
Speaking of the NASCAR package, one of the strengths of this personnel groups is its ability to use speed to stunt inside to confuse the interior offensive line and create confusion. The Patriots' guard pairing of Logan Mankins (who might be the best right guard in the NFL) and a future Hall of Fame candidate, Brian Waters, will help neutralize the interior pressure of the Giants DE stunts.
As for handling pressure off the edge, I envision New England using a lot of two tight end formations, flanking the tackles. Watch the Patriots tight ends to chip Osi Umenyiora and Pierre-Paul before releasing into their patterns. I wouldn't be surprised if the Patriots run alot out of this formation either, making the Giants even more reluctant to replace power with speed on their defensive line.
In terms of offensive personnel, look for the Giants to use a lot of three wide receiver sets to spread out the Giants defense and force linebackers like Kiwanuka into coverage. Speaking of coverage, based on the way Vernon Davis torched the Giants safeties in the NFC championship, watch for the Patriots to continue to use multiple formations with Gronkowski and Hernandez flexed away from the core of the formation to attack the Patriots defense.
While all of this sounds like I am predicting a Patriots victory, I'm not. I think the Giants will win based on the recent 4th quarter successes of Eli Manning and the ability of the Giants to rotate fresh pass rushers into the game to frustrate Tom Brady, both in base personnel and the aforementioned NASCAR package. I see an another flurry of second half offensive fireworks from both teams, ultimately resulting in a 24-21 Giants victory. Enjoy the game and the commercials!
