Running back, Minnesota Vikings
When you're desperate for a win, it makes sense to lean on your best player. That's exactly what the Vikings did on Sunday. Peterson rushed for 122 yards and three first-half touchdowns to lead Minnesota past the Cardinals 34-10.
Quarterback, Pittsburgh Steelers
A sore foot didn't appear to be an issue for Roethlisberger against Tennessee. Roethlisberger, who wore a boot on his sprained left foot for much of the week, tied a team record by tossing five TD passes in the Steelers' 38-17 rout. Big Ben finished 24-of-34 for 228 yards and was sacked only once.
Quarterback, Green Bay Packers
Rodgers continues to put up staggering numbers. A week after passing for a career-high 408 yards against Denver, Rodgers threw for 396 yards and two TDs in the Packers' 25-14 win at Atlanta. Rodgers completed passes to 12 different receivers.
Quarterback, Kansas City Chiefs
Cassel shook off a sluggish start and picked apart the Colts' defense. He threw four TD passes to lead the Chiefs to a 28-24 victory after falling behind by 17 points in the first half. Cassel was 21-of-29 for 257 yards and did not throw an interception.
Wide receiver, Kansas City Chiefs
Kanas City's big-play threat had his best performance of the season in the Chiefs' comeback win. Bowe caught seven passes for 128 yards and two TDs -- a 41-yarder in the second quarter and a 5-yarder in the third.
Quarterback, New Orleans Saints
Brees threw for 359 yards and two touchdowns, including a 6-yarder to Pierre Thomas with 50 seconds left, helping the Saints outlast Carolina 30-27. Brees completed eight of nine passes for 80 yards on the winning drive to take back momentum after Cam Newton and the Panthers had taken their first lead early in the fourth quarter.
Running back, New England Patriots
Green-Ellis had a career game against his team's fiercest rival. Green-Ellis rushed for a career-high 136 yards and two TDs on 27 carries in the Patriots' 30-21 victory over the Jets. It was his first 100-yard rushing game since Week 16 of last season.
Running back, Buffalo Bills
Another productive game by Jackson helped the Bills improve to 4-1. Jackson rushed for 111 yards and a TD, and caught six passes for 86 yards in Buffalo's 31-24 victory over the Eagles.
An opportunistic defense also helped the Bills' cause against Philadelphia. Linebacker Nick Barnett had two of Buffalo's four interceptions, including a 31-yard pick-six in the second quarter. The Bills forced five turnovers overall.
Cornerback, Seattle Seahawks
A wacky Giants-Seahawks game came down to a tipped pass, and Browner was in position to spoil New York's comeback. Browner intercepted an Eli Manning pass, which glanced off the hands of WR Victor Cruz, and raced 94 yards for a TD with just over a minute remaining to cement Seattle's 36-25 victory. Kam Chancellor and Earl Thomas also had interceptions for the Seahawks.
Wide receiver, Seattle Seahawks
Browner wasn't the only unlikely star for Seattle. Baldwin's 27-yard TD catch gave the Seahawks the lead for good with 2:27 left. Baldwin, an undrafted rookie from Stanford, finished with eight catches for 136 yards.
Quarterback, Philadelphia Eagles
Vick set the all-time rushing mark for quarterbacks on Sunday. That's about the only positive Vick can take away from his performance in Buffalo. Vick was intercepted a career-high four times and lost a fumble in the Eagles' fourth loss in a row. Vick had three of his first four possessions end with interceptions.
Quarterback, Arizona Cardinals
So far, the Cardinals aren't getting what they envisioned from Kolb. The pricey acquisition had another shaky outing in Week 5. Kolb turned the ball over three times (two INTs, one fumble) and completed only 21 of 42 passes in Arizona's loss in Minnesota.
Quarterback, Houston Texans
He passed for 416 yards, but one costly gaffe earns Schaub a spot on this list. With the Texans driving for a potential winning score, Schaub was intercepted by Michael Huff on the last play of the game, sealing Oakland's 25-20 victory. Schaub, who didn't have star WR Andre Johnson (hamstring injury),
threw six consecutive incompletions during one stretch of the final quarter.
Often a strength, the Giants' running game was held in check for the second week in a row. New York was held to 69 yards on 25 carries (a 2.8-yard average) in its loss to Seattle. The Giants rushed for only 54 yards last week in Arizona.
