Bengals' corners face another young QB

A week after giving up 322 yards passing to Cleveland's Brandon Weeden, the Bengals' cornerbacks face another rookie first-round quarterback in Robert Griffin III on Sunday.

Two games into the regular season, Leon Hall hasn't looked the same since injuring his Achilles last year, and Nate Clements (32 years old) and Terence Newman (34) have looked old. The Bengals' defense ranks 29th in completion percentage (71 percent), 29th in passing yards allowed (308.5), and 30th in passing first downs (31).

Last season, Cincinnati allowed only one team -- Seattle -- to throw for 300 yards. This season, both opponents (the Ravens and Browns) have topped that mark.

"It's just doing our jobs, being where we need to [be] all the time, being consistent," coach Marvin Lewis said. "We're pressing a little bit, and it showed."

Big plays allowed have always been a problem for the Bengals, and it's something that Lewis has tried to stress to his defense. The Bengals have given up 11 pass plays of more than 20 yards. Only the Saints, Bears and Buccaneers have allowed more.

The Bengals have to be wary of RG3's arm. His 9.6 yards per attempt leads the NFL.

Cincinnati's pass defense will get a boost if Carlos Dunlap returns after missing the first two games with a knee injury. He has 14 sacks in 24 career games.
