AFC North: QB watch

Evaluating what just happened and what lies ahead for the AFC North quarterbacks:


Last game: Dalton is coming off a bye. The previous week, he completed a season-high 78.1 percent of his throws (25-for-32) against the Colts. He finished with 264 yards passing, one touchdown and no interceptions.

QBR last game: 88.8 (fifth-best in NFL that week)

This Sunday: The Seahawks and the 20th-ranked pass defense in the NFL. Seattle has lost two cornerbacks for the season: starter Marcus Trufant and his replacement Walter Thurmond. In two home games, the Seahawks have given up 271.2 yards passing, allowing two touchdowns and intercepting two passes.



Last game: McCoy was held to a season-low 178 yards passing by a mediocre Seahawks secondary. It also marked the first time this season that he didn't throw a touchdown pass.

QBR last game: 31.5 (15th)

This Sunday: The 49ers and the 22nd-ranked pass defense. Before the bye, the 49ers gave up at least 290 yards passing in two of their previous three games. In two road games this season, McCoy has thrown for 425 yards with three touchdowns and no interceptions. But he could be without wide receiver Mohamed Massaquoi and tight end Ben Watson, who suffered concussions Sunday.



Last game: Flacco had a horrific game at Jacksonville, where he had 37 yards passing through three quarters. He finished with a season-low 137 yards passing. A week after having a season-best 9.2 yards-per-attempt, he produced a season-worst 3.6 YPA.

QBR last game: 20.2 (21st)

This Sunday: The Arizona Cardinals and the 28th-ranked pass defense in the league. The Cardinals have given up 30 plays of 20 yards or more, which is third-most in the NFL. Once again, wide receiver Lee Evans isn't expected to play because of an ankle injury.



Last game: Roethlisberger continues to heat up, throwing for 361 yards and three touchdowns. He also connected on the longest pass play in Steelers' history, a 95-yarder to Mike Wallace.

QBR last game: 89.9. (4th)

This Sunday: The New England Patriots and the NFL's worst pass defense. Look for Roethlisberger to go deep against the Patriots, who have given up a league-high 37 passes over 20 yards. That's six more than any other defense has allowed.
