Each week Studs & Duds will take a look at the best and worst match-ups from around the NFL and choose four players that could mean the difference between fantasy success or failure.

Based on the scoring system established by Yahoo!'s Flames and Lames, Studs and Duds can't seem to get back to a winning record. After going 2-6 in last week's picks, S&D's season record now stands at 30-34.  Do you have some of your own Studs and Duds in mind? If so, put your picks and predictions (no explanation for picks necessary) in the comment section below and see if you can beat us at our own game.

Studs

Matt Cassel / QB / Kansas City Chiefs- (vs. Jaguars) Although Cassel hasn't necessarily been the model of consistency this year, he'll provide owners with some solid stats during a week that once again will see six teams sporting a bye. The Chiefs will face-off against a Jaguars team that is allowing over 242 passing yards per game, and has also given up 13 passing scores. It also bodes well for Cassel that Kansas City is having problems with their running back situation, as it should lead to plenty passing opportunities. That's because starting RB Jamaal Charles will likely take a few drives or quarters to get used to his new role.

Prediction: 31-48, 278 passing yards, 2 total touchdowns, 0 interceptions, 9 rushing yards

Michael Crabtree / WR / San Francisco 49ers- (vs. Titans) Crabtree has looked very solid in his first two games with the 49ers. He gets a great match-up this week against the Titans who still rank as the worst pass defense in the NFL. QB Alex Smith has been solid since reclaiming his starting role, and Crabtree has been one of his favorite targets. If he's still available in your league, now would be the time to grab him since his stock is likely to soar. Considering that the WR has done great in two games against two solid pass defenses, owners shouldn't be surprised when he ranks as one of the top wide-outs this week.

Prediction: 8 receptions, 112 receiving yards, 1 touchdown

Clinton Portis / RB / Washington Redskins-(vs. Falcons) The Redskins are coming off their bye week, and that's very good news for Portis owners. With time to rest a few of the bumps and bruises that have been nagging him all year, he'll likely come out at or close to 100%. He'll face off a Falcons rush D that's been allowing over 121 rushing ypg, and has allowed almost 19 points per game to opposing RB's. If the Redskins' passing game is finally able to get their act together, then Portis could be in store for a huge fantasy day as a balanced attack will open a few more running holes.

Prediction:  22 carries, 96 rushing yards, 2 receptions, 17 receiving yards, 1 touchdown

Jason Witten / TE / Dallas Cowboys- (vs. Eagles) Witten did not perform as well as predicted last week, but this week he will redeem himself. In his career, Witten has done pretty well against the Eagles. Combine his past success with the fact that the Eagles are allowing almost 12 points per game to opposing TE's, and it's not hard to imagine Witten putting up solid fantasy numbers.

Prediction: 6 receptions, 80 yards, 1 touchdown

Duds

Ben Roethlisberger / QB / Pittsburgh Steelers- (vs. Broncos) Big Ben has put up solid fantasy numbers all year, but this week will be different. With the exception of his game against the Chargers, he has yet to face a real quality passing defense. Well, that's exactly what he'll see in the Broncos. Denver has the eighth ranked pass D, but the important number to consider is that they've only allowed 4 passing touchdowns. When you take into account how good the Broncos D has been with the fact that the Steelers will be on the road, Roethlisberger owners should definitely prepare for a dud-worthy week.

Prediction: 17-34, 165 passing yards, 1 touchdown, 1 interception, 4 rushing yards

Roddy White / WR / Atlanta Falcons- (vs. Redskins) White has managed to haul in a touchdown in five of his last six games, helping to make him one of the top fantasy WR's of the year. Despite that, His value will take a hit this week, as he faces a tough Washington pass D. The Redskins are only allowing 165 passing ypg, and have only allowed six passing TD's. White will have trouble getting open as it's likely he'll be double teamed most of the day. If that's the case, he could easily put up his worst fantasy day of the year, and cause plenty of grief for owner's who feel compelled to start him despite the tough match-up.

Prediction: 4 receptions, 38 receiving yards, 0 touchdowns

Ronnie Brown / RB / Miami Dolphins- (vs. Patriots) Brown is a very poor play this week for a few reasons. First of all, he has no rushing touchdowns on the road this year as all seven of his scores have come at home. With the Dolphins rolling into Gillette to face a tough Patriots defense, he's likely to stay on that current trend. Secondly, New England has only allowed one rushing TD on the year. Finally, Brown managed just 47 total yards in his last game against the Patriots. After considering all of those factors it just seems foolish to risk playing Brown. It's easy to predict that the Patriots will be able to tame the Dolphins' wildcat.

Prediction: 13 carries, 61 rushing yards, 2 receptions, 16 receiving yards, 0 touchdowns

Jeremy Shockey / TE / New Orleans Saints- (vs. Panthers) Shockey has put up three stud-worthy games in a row as the Saints have managed to remain undefeated in '09. Although the Saints will likely roll to their eighth win of the year, Shockey won't contribute much from a statistical standpoint. The Panthers have the top ranked pass D, and it's unlikely the Saints will throw as often as they have in past games. That's because Carolina has the 24th ranked rushing defense. New Orleans will rely heavily on their trio of strong RB's to help carry them to victory, and that means Shockey will do more blocking than receiving in week nine.

Prediction: 3 reception, 35 receiving yards, 0 touchdowns
