Running back, Minnesota Vikings
Peterson continues to churn out eye-popping performances. Peterson, who has become a staple on this list, rushed for 212 yards on 24 carries, powering the Vikings to a 36-22 victory over St. Louis. Peterson's 82-yard touchdown run in the second quarter gave Minnesota the lead for good. It was his second 200-yard game in three weeks. He's now 294 yards shy of breaking Eric Dickerson's single-season rushing-yards record of 2,105.
Quarterback, Atlanta Falcons
Under pressure to deliver a dominant victory, Ryan and the Falcons didn't disappoint Sunday. Ryan completed 23 of 28 passes for 270 yards and three touchdowns in a 34-0 drubbing of the Giants.
Quarterback/wide receiver, San Francisco 49ers
Big plays by Kaepernick and Crabtree helped the 49ers escape New England with a 41-34 victory. Crabtree (7 catches, 107 yards) caught two TD passes from Kaepernick, including a late 38-yarder that proved to be the game-winner. Kaepernick (14-of-25, 216 yards) had two other TD passes -- first-half strikes to Randy Moss and Delanie Walker.
Quarterback, New Orleans Saints
The Buccaneers' porous pass defense was good medicine for Brees, whose previous three outings were far from his usual standards. Brees threw for 307 yards and four scores without an interception in the Saints' 41-0 victory.
Defensive end, Houston Texans
In a game that clinched the AFC South title for the Texans, Watt might have clinched the NFL Defensive Player of the Year award. Watt had three sacks, a forced fumble and six tackles for loss in Houston's 29-17 victory over the Colts.
Running back, Houston Texans
Foster also came up big for the Texans. Foster rushed for a season-high 165 yards on 27 carries, giving him his third straight season with at least 1,200 yards rushing. He now has 1,313 yards on the season.
Cornerback, Dallas Cowboys
Signed as a free agent this past offseason, Carr rewarded the Cowboys handsomely Sunday. Carr's overtime interception of Ben Roethlisberger (and subsequent 36-yard return) set up Dan Bailey's winning field goal in a 27-24 victory.
Quarterback, Washington Redskins
A quarterback controversy in Washington? We're kidding, but Cousins was solid subbing for the banged-up Robert Griffin III. Cousins threw for 329 yards and two touchdowns, leading the Redskins to their fifth straight win, 38-21 over Cleveland.
Wide receiver, Green Bay Packers
A nonfactor in recent weeks, Jones broke out against the Bears. Jones caught all three of Aaron Rodgers' TD passes in Green Bay's 21-13, NFC North-clinching victory.
Led by rookie QB Russell Wilson, the Seahawks ran all over a hapless Buffalo defense. Wilson rushed for first-half scores of 14, 25 and 13 yards as Seattle piled up 270 rushing yards in a 50-17 rout. Marshawn Lynch had 113 of those yards and a score.
Maybe fired offensive coordinator Cam Cameron wasn't the problem after all. The Ravens, in their first game with Jim Caldwell calling the plays, were stymied for most of Sunday's 34-17 loss to Denver. Baltimore didn't get a first down until eight minutes left in the first half and didn't reach the end zone until the fourth quarter. Joe Flacco lost a fumble and had an interception returned 98 yards for a score by Chris Harris.
Quarterback/running back, Tampa Bay Buccaneers
Freeman endured one of the worst outings of his career, throwing four interceptions and losing a fumble in the Buccaneers' fourth straight loss. The Saints also bottled up Martin, holding the normally stout rookie to a season-low 16 rushing yards on nine carries.
Can it get any worse for the Chiefs? In one of the true dud games of the season, Kansas City mustered only 119 total yards and lost to Oakland 15-0. Jamaal Charles, coming off three straight games with at least 107 rushing yards, was held to 10 yards on nine carries.
Quarterback, Detroit Lions
Stafford threw three interceptions -- his first three-INT game since opening day -- as the Lions fell in Arizona 38-10. Stafford's third pick was returned 102 yards for a touchdown by Greg Toler.
Quarterback, New York Giants
Manning was intercepted on his first pass attempt of the game. Things didn't get much better after that. Manning threw a second pick and completed only 13 passes in the Giants' loss.
