While hitting it big in tournaments is appealing to the casual DraftKings player, simply doubling your money in cash games is a great way to build a bankroll. Here are the plays I like for the 12-game Week 4 main slate on DK:
QB 
Patrick Mahomes ($7,500) @DET — He’s the closest thing to buying 30 DKFP you can find. First NFL game in a dome (where he thrived in college games) gives him another boost.
Russell Wilson ($6,100) @ARI — One of the worst defenses against QBs, and the offense keeps the pace of play moving. Russ coming off 40-plus DKFP, and we can’t trust this running game.
Daniel Jones ($5,300) vs. WAS — Danny Dimes will be a popular play while he’s underpriced. A matchup against Washington should keep the hype train rolling with another big game. Saquon’s absence gives Jones more rushing upside.
RB
Christian McCaffrey ($8,800) @HOU — The safest play on the board, always looking at 25 touches. Still underpriced.
Austin Ekeler ($8,000) @MIA — Justin Jackson is out. Even if Melvin Gordon plays, it won’t be much. Chargers could run Ekeler into the ground, now that he’ll be shifting into at least a time-share with Gordon moving forward. Oh yeah, they play the Dolphins.
David Johnson ($6,800) vs. SEA — Averaged 19.5 touches and 22 DKFP if you take out the game he got hurt. Fast paced game coming against Seattle.
Nick Chubb ($6,400) @BAL — His transition into an every-down RB last week against the Rams gives him a safer floor. Got seven targets on SNF, playing all but one snap.
Kerryon Johnson ($5,400) vs. KC — His role is on the rise with C.J. Anderson gone. Should be playing from behind against KC, but his YPC has good upside.
Wayne Gallman ($4,600) vs. WAS — The obvious salary saver with Saquon out. Gallman won’t have what it takes to be the featured RB all season, but can handle 15 touches against a terrible Washington defense.
WR
Keenan Allen ($7,600) @MIA — Guy’s been dominating this season, and now plays in Miami. Has seen 42 targets, and now Mike Williams is out, and Travis Benjamin is unlikely to play.
Cooper Kupp ($6,500) vs. TB — Very trustworthy option, and has seen at least nine targets in every game. Goff’s a better QB at home, and Tampa secondary is weak.
Tyler Lockett ($6,300) @ARI — Good play to pair if you play Wilson. Monster target share the last two weeks after flukey Week 1.
Christian Kirk ($5,100) vs. SEA — A cheaper piece to play to get exposure to the passing game in Arizona. Still no trips to the end zone, but should change soon.
WAS WR vs. NYG — This is an interesting spot, as Terry McLaurin ($4,500) has been the play all week. He’s questionable with a hamstring injury now, making him a dicey cash play if he suits up. Now Paul Richardson ($3,700) and Trey Quinn ($3,000) have to be consideration.
TE
Travis Kelce ($7,200) @DET — I won’t have the salary to pay this much at TE, but he is a safe cash play if your build leaves you the room for him.
Evan Engram ($5,700) vs. WAS — Having a great season, and was on the same page with Jones last week for 6-113-1. WAS defense stinks, as you know by now.
Darren Waller ($5,200) @IND — Coming off his best game of the season, and will face an IND defense missing a ton of important players. Safe floor.
Will Dissly ($3,600) — This is the spot to save at TE this week. Has been targeted 12 times and scored three touchdowns in the last two weeks.
D/ST
Chargers ($3,800) @MIA — They play the Dolphins.
Patriots ($3,700) @BUF — Most talented defense in the league, and averaging the most DKFP.
Rams ($3,500) vs. TB — Dominated the Browns on the road, so the Bucs at home should be an even easier task.
