Every week, I highlight a few players to start and a few players to sit at each position. I’m a firm believer in starting your studs, so I won’t suggest you bench Drew Brees or Adrian Peterson because they have tough matchups – just go ahead and keep them in your lineup. Instead, I’ll focus on the borderline guys – players you’ll only start under the right circumstances.

As usual, I’ll discuss these players within the context of my weekly positional rankings, so remember — everything is relative.

Joe Flacco has been really good lately (267 yards, 2.0 pass TDs over his last seven games) and he has a matchup with the worst pass defense in the league. Good things should happen…Even with Asante Samuel back for the Eagles, I still like Jon Kitna this week. The Eagles have given up 24 pass TDs on the season and this one is shaping up to be a shootout…Josh Freeman should have a nice day against the Redskins, who have struggled all season against the pass. Washington has given up an average of 32 points over the last five games, so Freeman should find the endzone once or twice…Need a spot starter off the waiver wire? Alex Smith is back under center for the 49ers and he has an outstanding matchup against the Seahawks’ 30th-ranked pass defense.

I love Knowshon Moreno this week. Not only is he hot (averaging 142 total yards and 0.75 TDs per game over the last four weeks), but he has a matchup with the Cardinals, who are terrible against opposing RBs…There is some scuttlebutt about Earnest Graham stealing goal line carries, but it shouldn’t matter that much this week as LeGarrette Blount has a great matchup with the Redskins, who have given up an average of 137 yards and 1.0 TD on the ground this season…Tashard Choice might be available on the waiver wire, and he is coming off a nice game against the Colts. The Cowboys will use the same run-heavy attack to try to keep Mike Vick on the sidelines this Sunday, so I’m expecting another solid outing (70-80 total yards and a score) out of Choice this week.

After a slow start, Marques Colston has been playing good football for the last six games, and with a W14 matchup against a Rams’ defense that has struggled against opposing WRs, I’m expecting a good game. Colston always has some downside due to Drew Brees‘s propensity to spread the ball around, but everything points to a good fantasy line…With Dez Bryant sidelined, I’d get Miles Austin (and to a lesser extent, Roy Williams) into lineups this week. Austin should go back to fringe WR1 status (though Asante Samuel’s return to the Eagles’ secondary is a little worrisome), while Williams is a guy that’s available on a lot of waiver wires…Michael Crabtree should benefit from Alex Smith’s return to the lineup and a matchup with the Seahawks, who have given up a ton of fantasy points to opposing WRs this season…Need a deep sleeper? How about Deon Butler, who may get WR1 targets if Mike Williams and Ben Obomanu are sidelined.

Matt Cassel is iffy (likely out) after an appendectomy earlier this week and he had a bad matchup to begin with. Stay away…Whatever confidence I had in Mark Sanchez is gone after his debacle in a great matchup against the Pats on Monday night. The Dolphins’ pass defense is pretty good, so I’m not betting on a big bounce-back game from the Sanchize…Sam Bradford had his first below average game in quite a while and the Saints have been tough on QBs all year. He’s okay in a pinch, but I’m not expecting much this week.

LaDainian Tomlinson hasn’t topped 63 total yards in the last two weeks and hasn’t scored a TD since W6. Shonn Greene is eating into his carries and the Dolphins are not a particularly good matchup for RBs…Cedric Benson grinded out 74 total yards and a TD against the Steelers in their first meeting, but Pittsburgh has the #1 rushing defense in the league, so I’m not expecting a repeat of those numbers (at least not the TD) this week…Marshawn Lynch was a fantasy stud last week, but I doubt too many people had him in their lineups. This week, he has the 49ers, who are #10 in rushing yards allowed and have only given up seven rushing TDs all season.

He’s still startable, but Dwayne Bowe is no longer a no-brainer, not with Matt Cassel likely out and his goose egg last week. Throw in a date with the Chargers, who have done well against opposing WRs this season, and there are warning signs everywhere…The Titans say they are going to ‘ease’ Kenny Britt into the offense, so wait at least a week to put him in your starting lineup. Plus, the Colts are pretty good against the pass…Brandon Marshall may be back, but he may have Darrelle Revis shadowing him, and that’s not a good thing.
