Week 15 Start 'Em Sit 'Em: Carson Palmer and Must-Sit QBs

A star quarterback who drops the ball for your fantasy team is often the difference between winning and losing in the fast-paced, short-lived world of fantasy football playoffs.

Carson Palmer is one signal-caller poised for a disappointing outing in Week 15. Palmer threw four interceptions last week against Green Bay and has more INTs than TDs thus far in 2011.

The Detroit Lions defense will make life tough again for Palmer this Sunday in Oakland, when they return Ndamukong Suh to the starting lineup and look to force the former Bengals QB into mistakes he's used to making time and again.

But Palmer's not the only must-sit QB in Week 15, here are some others:

Joe Flacco (BAL)

Ray Rice is balling right now, at a very high level. Cam Cameron and the Ravens' offensive coaching staff do make confusing decisions from time to time, but they aren't stupid. 

If Rice is getting touches, Flacco isn't; it's that simple. Flacco has a big arm, but he's hardly been the stat guy this season that people expect him to become down the road.

Flacco is averaging less than 10 fantasy points in ESPN standard leagues the past three weeks, and that number shouldn't change significantly against the Chargers in San Diego on Sunday night.

Flacco's talent warrants a start if you're depleted at QB, but his matchup and support in the backfield suggest he's more useful on the bench in Week 15.

Mark Sanchez (NYJ)

Do not be fooled by the dominant play of the Jets of late. After all they were beaten by an offense-less Broncos team just last month.

Sure, Mark Sanchez is averaging just under 19 fantasy points per week in ESPN standard leagues, but that was against hopeless squads like Buffalo, Washington and Kansas City.

He'll try his talents against yet another depleted opponent on Sunday in Philadelphia, but still a more capable defense than the ones he has been facing in recent weeks.

Sanchez can turn the ball over like clockwork from time to time, and that can take points away from your fantasy team.

The bottom line is that Sanchez has gone two weeks without throwing a pick. He's due. 

Philip Rivers (SD)

The Chargers take on the league's fifth-most stingy pass defense this season in the Baltimore Ravens on Sunday night.

It's safe to say that the Bolts' two-game winning streak will come to an end, but even easier to say that San Diego QB Philip Rivers will struggle mightily against Ed Reed and company.

Rivers has been nearly flawless the past two weeks for the Chargers, throwing six TDs to no interceptions, but that was against Jacksonville and Buffalo.

Neither of those defenses compare to that of Baltimore, and the Ravens have arguably more to play for and more at stake at this stage in the game than the wild-card-hopeful Chargers.

Baltimore is and will continue to be on a mission in Week 15 in southern California, making Rivers a very shaky start for any fantasy owner, even the bold.
