Marcell Dareus records two sacks and the team surrenders only 24 yards rushing as Buffalo defeats Baltimore on Sunday.

Quarterbacks: A game like this can be a positive learning experience for EJ Manuel, as it featured some memorable and not so memorable plays from the talented rookie. The second quarter touchdown to Woods was an outstanding throw, but his two interceptions, particularly the one in the third quarter, could have been avoided. C

Running Backs: The duo of Fred Jackson and CJ Spiller found open running room against the talented Raven defense, combining for 164 yards and a touchdown. Jackson was particularly effective, recording 5.4 yards per carry and a 16-yard touchdown run in the second quarter. B

Wide Receivers: Sunday was a nice coming out party for rookie Robert Woods, who finished with four catches for 80 yards including a 42-yard touchdown in the second quarter. He didn't have much help though as the rest of the core only three catches, including Stevie Johnson with just one reception for -1 yards. B-

Offensive Line: It may not have been a game to remember for Cordy Glenn, but the rest of the line was stout against a tough Baltimore defensive line. They helped pave the way for an impressive ground attack registering 203 yards. B

Defensive Line: The Bills defensive line controlled the line of scrimmage as the Ravens with just 24 yards rushing on nine carries. Marcell Dareus was key against the run (seven tackles) and in the passing game recording two sacks. A-

Linebackers: Kiko Alonso continues his campaign for defensive rookie of the year award, as he recorded two interceptions including the game-clincher with 1:04 remaining. Manny Lawson was also stout, tallying five tackles and a sack. B+

Secondary: Joe Flacco had decent yards (347) and completions (25) but the Bills revamped secondary picked him off three times with Aaron Williams recording two. Not bad considering the team had four new starters including former Raven Jim Leonhard, who also had an interception. A-

Special Teams: Not too much out of the return game, but Dan Carpenter was solid connecting on all three of his field goal attempts. Punter Shawn Powell averaged over 43 yards per punt on eight punts and landed three punts inside the 20. B

Coaching: Doug Marrone earned his second win and did it against the defending Super Bowl champion, but they were still enough disappointing moments that he will need to learn from. Punting from the Baltimore 38 up 13 in the second quarter, with the defense playing well, was far too conservative. C+
