Bargain Plays - Wild Card Weekend's Top Sleeper Picks
Here are the top sleeper plays for Wild Card weekend:

QB AJ McCarron, Bengals (vs. Steelers)
McCarron is one of the cheaper options at QB. Unlike Teddy Bridgewater, he stands a decent chance at returning solid value.
First, he has WR A.J. Green, who torched the Steelers for 250 yards and two TDs over two games in the regular season. Second, McCarron hasn't thrown an interception in three weeks, showing solid improvement.
McCarron could be relied heavily upon with RBs Jeremy Hill and Giovani Bernard having struggled against Pittsburgh. He'll need to pick up more yards to be worth rostering, but his low salary opens up a load of other options.

RB James Starks, Packers (at Redskins)
Of all the Wild Card weekend teams, the Redskins fare the worst against the run, allowing 4.8 yards per carry. Only the Saints were worse. Washington only surrendered 10 rushing TDs, but that could be anomalous considering how easily teams steamrolled their run D.
Starks is on a time share and costs less than teammate Eddie Lacy. Over the course of the season, Starks amassed as many touchdowns as Lacy with five and only totaled 157 fewer rushing yards. Go with Starks because of his price and his occasional ability to hit it big.

WR Davante Adams, Packers (at Redskins)
Adams has increased his yardage output for three consecutive weeks heading into the postseason. The Packers match up fairly well with the Redskins' secondary, and while Randall Cobb will likely be expected to be the top target with James Jones as an alternate, Adams is the wild card.
Having only caught a single TD all season, Adams has seen his DFS salary plummet. He's worth a flier in GPPs because of his price and the possibility of extremely low ownership.

TE Kyle Rudolph, Vikings (vs. Seahawks)
Rudolph is a high-risk flier, no doubt. He needs Bridgewater to have an effective game, which might be asking too much. Rudolph's last meeting with the Seahawks saw him haul in only three catches for 13 yards.
So while Rudolph's recent play has been less than encouraging, he won't eat up a lot of salary and there is TD upside. You could pay nearly twice as much for a Jordan Reed or you could roll with Rudolph and go with steadier hands throughout your lineup. If he catches a TD, he'll be worth the investment.
