"Being a two-time Super Bowl champion, Phil Simms knows a thing or two about what it takes to win in January, and he thinks Ravens quarterback Joe Flacco did more than enough last Sunday.

Simms, a former quarterback of the New York Giants who will provide color commentary during CBS's broadcast of Sunday's AFC championship game (Jim Nantz will handle play-by-play duties), said on a national conference call Tuesday that Flacco played "very well" in the 20-13 divisional round victory against the Houston Texans, even though his final stat line wasn't very impressive.

He believes the New England Patriots will be wary of Flacco's big arm and big-play ability Sunday.

"I'm sure the Patriots are thinking, 'Man, we better not let anyone behind us,'" Simms said.

Against the Texans, Flacco completed 51.9 percent of his 27 attempts for 176 yards and a pair of touchdowns — giving him a 97.1 passer rating. But Baltimore scored just three points after the first quarter. Simms said Houston's second-ranked defense deserves some credit for that.

Still, there is concern whether the Ravens can keep up with Tom Brady and the high-scoring Patriots, who are averaging 37.3 points per game during their current nine-game winning streak. Brady threw six touchdown passes in their 45-10 win over the Denver Broncos last Saturday."
