Quarterback, Dallas Cowboys
Romo could have called it a day at halftime and still made this list. Romo completed 18 of 19 first-half passes for 237 yards and three touchdowns, giving the Cowboys a commanding lead in their 44-7 victory over Buffalo. Romo finished 23-of-26 for 270 yards; he set the franchise record for single-game accuracy (88.5 percent).
Running back, Houston Texans
Another productive game by Foster helped the Texans trounce Tampa Bay. Foster had 186 total yards and scored a pair of TDs in Houston's 37-9 victory. He had a 78-yard receiving TD in the second quarter and scored on a 5-yard run in the third quarter.
The Texans' top-ranked defense also had a big hand in Sunday's victory. Houston made life miserable for Bucs QB Josh Freeman (see below), intercepting him three times and sacking him four times. The Texans, who limited Tampa Bay to 231 total yards, also pried a fumble away from Bucs backup QB Josh Johnson late in the fourth quarter.
Speaking of defense, the Steelers' D shined late in Cincinnati. Pittsburgh, which had picked off only two passes all season, intercepted Bengals QB Andy Dalton twice in the fourth quarter to seal a 24-17 victory. William Gay had the clincher when he stepped in front of Jerome Simpson inside the 20-yard line with 2:27 left.
Tight end, New England Patriots
The Patriots might lack a true deep threat, but what they do have is a premier red zone target in Gronkowski. The second-year tight end caught TD passes of 18 and 5 yards in the Patriots' 37-16 victory over the Jets. He finished with eight catches for 113 yards.
Quarterback, New England Patriots
Brady delivered a vintage performance Sunday night, completing 26 of 39 passes for 329 yards and three TDs without an interception. It was the 40th time Brady reached the 300-yard mark in a regular-season game, breaking a tie with Hall of Famer Joe Montana for eighth on the NFL's list.
Wide receiver, Arizona Cardinals
It doesn't seem to matter who plays quarterback for the Cardinals -- Fitzgerald finds a way to make an impact. Fitzgerald had two TD catches and made a sensational, over-the-shoulder diving catch to set up the go-ahead score in Arizona's 21-17 victory at Philadelphia. Fitzgerald finished with seven receptions for a season-high 146 yards.
What do you do when your quarterback's a work in progress? You run the ball -- a lot. Playing the majority of the game without Willis McGahee (hamstring), the Broncos piled up 244 yards on 55 carries in a 17-10 victory at Kansas City. Quarterback Tim Tebow had 43 of those yards, including a 7-yard TD run, on nine carries.
Running back, Tennessee Titans
Maligned for most of the season, Johnson finally got on track in the Titans' 30-3 rout of Carolina.
Johnson rushed for 130 yards and a TD and had four catches for 44 yards.
Cornerback, San Francisco 49ers
Rogers continues to affirm his status as one of the top free-agent pickups of the offseason. Rogers intercepted two Eli Manning passes and had six tackles in the 49ers' 27-20 victory over the Giants.
Quarterback, Philadelphia Eagles
On a day when the Eagles pretty much played themselves out of playoff contention, Vick had perhaps his worst game of the season. Minus big-play threat DeSean Jackson, Vick threw two interceptions, had one overturned on replay and another called back for holding. He averaged 3.8 yards per pass attempt and never could find a rhythm.
Quarterback, Detroit Lions
Wearing gloves on a warm day (he has an injured finger on his right hand), Stafford struggled with accuracy for much of Detroit's 37-13 loss in Chicago. Stafford threw four interceptions, two of which the Bears returned for scores to put the game away in the third quarter.
Wide receiver, Atlanta Falcons
White, who was held to four catches in the Falcons' 26-23 overtime loss to New Orleans, had a pass go off his hands in the fourth quarter that turned into a Saints interception. He also was flagged for two penalties away from the play. One of the league's best wideouts last season, White has only three TD catches in 2011.
Quarterback, Tampa Bay Buccaneers
Freeman's three-interception day sent Tampa Bay tumbling to its third straight loss. Freeman, who completed only 15 of 35 passes for 170 yards, had a season-worst 31.8 passer rating.
With certain victory in their grasp, the Browns let it slip away with one snap. Phil Dawson's 22-yard field goal attempt sailed wide left following a bounced snap from center with just more than two minutes left, allowing St. Louis to escape with a 13-12 win. Long-snapper Ryan Pontbriand's snap appeared to hit the right leg of center Alex Mack, who lines up at left guard for field goal attempts. The ball skipped back to holder Brad Maynard and affected Dawson's timing on the chip-shot kick.
