Fantasy football advice, Week 6: Who to start/sit for Washington vs. Cardinals

The Arizona Cardinals have been good this year, sitting at 3-1 and tied for the NFC West's best record. Washington has been really bad, with four losses in five games and one of the worst records in the NFC. Those two teams face off Sunday, in a matchup of teams going in different directions.

The teams have several injuries worth mentioning. Washington is still without quarterback Robert Griffin III, while tight end Jordan Reed is expected to make his return from a long-term hamstring injury. For Arizona, running back Andre Ellington has been limited with a foot injury, but is expected to be fine for the game. More crucially, the team's quarterback situation is up in the air. Drew Stanton has been cleared to play after suffering a concussion a week ago, while Carson Palmer still has some work to do to prove he can go, at last update.

Start 'em: Monday's game made Alfred Morris look bad, but he'd averaged 12.5 fantasy points a game before that. He's a must-start.

Start 'em?: Against a good Arizona defense, even with it missing some pieces, Pierre Garcon and DeSean Jackson are tough to count on, given their inconsistency this year. They're both low-end flex plays. ... The Washington tight end situation is a crapshoot. Both Jordan Reed and Niles Paul could be good fantasy plays on their own, but with them both likely to play Sunday, who can say if either one will get enough attention to trust?

Sit 'em: A three-game fantasy line of 27-5-19 makes it tough to predict what Kirk Cousins will do in any given game, but the main takeaway is that his downside really outweighs his upside. ... Kai Forbath has five or fewer fantasy points in three of five games this season. ... The Washington defense has negative-5 combined points the last three weeks.

Start in every league: Alfred Morris

Start if you're desperate: Pierre Garcon, DeSean Jackson, Jordan Reed, Niles Paul

Start 'em: Considering all the quarterback problems in Arizona, Andre Ellington seems likely to get heavy usage Sunday. He needs to be in all lineups. ... I'm still a believer in Michael Floyd, though it's starting to fade -- he needs to offer more consistency. ... Chandler Catanzaro has been the best new kicker in the league this year. He's a must-start.

Start 'em?: It's much harder to believe in Larry Fitzgerald at this point, with 13 total fantasy points in four games. You can only use him if you're super desperate. ... The Cardinals' defense is losing players to injury right and left; if the super-bad version of Cousins shows up, the unit could still do well, but it's far from a guarantee.

Sit 'em: We don't really know who is going to start at quarterback for Arizona Sunday -- heck, Bruce Arians might not know. But whether it's Carson Palmer, Drew Stanton or even Logan Thomas, even in a good matchup, you can't possibly trust any of them. ... John Carlson has 10 total fantasy points this season. Stay away.
