"Joe Flacco's 97-yard touchdown drive on the Ravens' first possession Sunday was impressive on a number of levels. The fourth-year quarterback completed seven of eight passes for 82 yards, throwing to four different receivers in every direction. He finished off the near-nine minute drive with a sneak for the touchdown.

But what made that drive so much more impressive was the fact that Flacco was getting drilled by a Houston defense that plays in the same aggressive, physical style as the Ravens.

In his Monday news conference, coach John Harbaugh was concerned about the number of times the Texans got to Flacco.

"The thing that was a little bit disappointing was our pass protection," Harbaugh said. "I think Joe made some great throws, especially in that first drive, and he got hit every single time. And that's not good. I think it's a testament to Joe and his toughness and all that. We've seen it. But we don't want Joe getting hit like that."
