THREE THINGS THAT NEED TO GO RIGHT ...
Ravens' run defense continues its domination. The Ravens impose their will on teams when they take away the ground game. If the top-ranked run defense can do that to the top-ranked ground attack, the Ravens will send a strong message.
Supporting cast steps up in passing game. Even if Derrick Mason (dislocated shoulder) plays, the Ravens' leading receiver won't be at full strength. The Ravens need someone - Todd Heap, Mark Clayton or Yamon Figurs - to fill the void for Joe Flacco's most dependable target.
Keep forcing turnovers. In the past two games, the defense has forced six, which has led to 28 points. This could be a big bonus against a Giants offense that is tied for second in the NFL in fewest giveaways (nine).
... AND THREE THINGS THAT COULD GO WRONG
Eli Manning follows brother's footsteps. The Ravens' banged-up secondary would be in serious trouble if Eli starts throwing the same pinpoint passes that Peyton did five games ago.
Giants crack Ravens' red zone defense. With a power back (Brandon Jacobs) and a leaping receiver (Plaxico Burress), the Giants have the weapons to solve the NFL's best. When backed up inside their 20-yard line, the Ravens have allowed touchdowns only 33 percent of the time.
Ravens' offensive tackles collapse under pressure. The Giants generate most of their pressure from their defensive ends (Justin Tuck and Mathias Kiwanuka). The Ravens' beat-up tackles - Jared Gaither, Willie Anderson and Adam Terry - could get Flacco hurt if they are a step slow.
