What’s the key for the Ravens to emerge victorious in Foxboro on Sunday?

That depends on who you talk to.

Some people think that containing Rob Gronkowski and Aaron Hernandez is the key. Some think that keeping Tom Brady off the field with long drives though a ground and pound running game is the key. But for FOX Sports’ Brian Billick, it all rests on the shoulders of Ravens quarterback Joe Flacco.

“Joe Flacco is going to have to step up in a big way and make a difference in this game for the Baltimore Ravens,” Billick said in his AFC Championship Preview.

The former Ravens coach acknowledged that the Ravens have gone into New England in the playoffs and won before and says that he doesn’t think they will be intimidated.

“I think Baltimore can do it,” he concluded.
