WATCH: Why Landry is among Week 9’s ‘Blazin’ game day picks.

The concept behind stacking a QB with his WR is simple: both players benefit from each completion, doubling the benefit of that play for your fantasy lineup. As Adam Levitan pointed out this offseason, 79 percent of the lineups that won DraftKings’ Fantasy Football Millionaire contests used a QB stack in their lineup. With the significance of stacking in mind, this article aims to highlight the best stacking options for Sunday’s main slate.

There are a lot of high-value discounts this week – some caused by trades, others by injuries or depth chart changes. Correctly stacking a QB and WR can help maximize the value of correctly identifying which discounts will be most successful.

5. Ryan Fitzpatrick ($5,500)/DeSean Jackson ($5,000), TB at CAR

The Buccaneers flip-flopping on their starting QB has dropped Fitzpatrick’s salary to the point where he is the 16th most expensive QB – despite starting just four games, he’s scored the 19th most DKFP this season. In his first three starts, he scored more than 30 DKFP. I wouldn’t recommend using this stack in cash games, but for a GPPs, the upside combined with his value salary is tremendous.

Jackson gets the nod as Fitzpatrick’s running mate for a few reasons. Chris Godwin ($4,400) might be a better discount, but his role and his floor are both significantly smaller, while Mike Evans ($8,100) is borderline overpriced. Second, while his role didn’t change much when Jameis Winston was QB in Weeks 6 and 7, in 2017 Jackson was more consistently productive during Fitzpatrick’s starts than those of Winston.

4. Alex Smith ($5,000)/Paul Richardson ($3,800), WAS vs. ATL

After Jordan Reed’s ($4,800) 12-target, 7-catch re-breakout in Week 8, Reed is actually the Redskins’ pass-catcher I’m most interested in. But this article is designed to focus on WRs, so we’re focusing on Richardson here. Richardson sat out Week 7, but his workload in Weeks 5, 6 and 8 were almost identical. Five targets and between 30 and 50 yards in each game, including one 20-plus yard reception in every contest.

With Jamison Crowder (ankle) looking likely to miss his fourth straight game, Richardson is roughly tied with Josh Doctson ($4,200) for the No. 1 WR role – except Richardson saves $400 in salary and is regularly involved in big plays, while Doctson only has zero 20-yard plays this season. Meanwhile, the Falcons’ undermanned defense continues to struggle, allowing every starting QB except Nick Foles to score at least 22 DKFP against them.

3. Jared Goff ($6,000)/Robert Woods ($7,000), LAR at NO

In a perfect world, Woods would cost a lot less. But this article already has plenty of discount options listed, and other than the No. 1 stack listed below, this is my favorite higher-end play of the week. And while Woods is bordering on expensive, Goff is an amazing discount. Goff is fifth among QBs in DKFP scored this season, and the Saints have already given up multiple 40-plus DKFP games to QBs. Goff also provides a safe floor. Though the Saints’ defense is improving, they’ve allowed at least 15 DKFP to every opposing starter – including Tyrod Taylor and Eli Manning.

The Rams are expected to get Cooper Kupp (knee; $6,000) back from a two-game absence this week, but that probably helps Woods. Woods’ target share did not change with Kupp out, and Woods’ yardage from those two games were his second- and third-worst of the season. Kupp’s return makes life harder on opposing defenses, which helps Woods. Woods has seen at least five catches and 70 yards in every game since Week 1, so he also provides a very strong production floor.

2. Case Keenum ($4,900)/Courtland Sutton ($3,900) DEN vs. HOU

No one is thrilled about starting a pair of Broncos, but this might be the cheapest reasonable stack I’ve seen all season. If you’re someone who wants to keep starting Todd Gurley ($9,500) and Adam Thielen ($8,900) until their magical rides end, Keenum and Sutton will give your roster enough salary relief that you can still consider some other high-end options.

The Texans’ defense is pretty good, but they are much better against the run than the pass. Keenum has had three rough games, but two of those were against the Cardinals and Ravens, both among the best defensive units in the NFL. And when Keenum has been good, he’s often been very good. He’s topped 15 DKFP in his five other games, and he’s reached 20 DKFP in three of those. Keenum has not thrown multiple INTs in a game since Week 1, and he has seven TDs in his last four games.

Meanwhile, the main attraction here is Sutton. Sutton was already starting to attract some fantasy attention after five straight games of at least eight DKFP. Now that the Broncos have traded away Demaryius Thomas ($4,500), Sutton takes over as the clear starter and No. 2 WR behind Emmanuel Sanders ($6,400). Thomas vacates seven targets per game, and with Sanders already averaging 8.1 per game, the assumption is that the majority of Thomas’ old work goes to Sutton. Sanders’ value also increases, and he’s a safer option than Sutton, though Sanders’ DFS upside is far less due to his 64 percent higher salary.

1. Cam Newton ($6,600)/ Devin Funchess ($5,600) & D.J. Moore ($4,300), CAR vs. TB

The thing I love about the Buccaneers is, while their opponent changes, they stay the same bad. Poorly adapted Matthew McConaughey quotes aside, the Buccaneers defense really is terrible, and there is no salary that could stop me from rostering their opponents in any given week. And these salaries aren’t even bad! Newton is still below his max salary this season, and Funchess is only $200 more than he was against the Ravens, probably the league’s best defense, in Week 8. Moore’s salary increase is in line with his production increase and does not show obvious signs of opponent-based inflation.

A quick statistical rundown of just how bad the Bucs have been: They rank dead last in points allowed, defensive DVOA and pass defense DVOA. They are second-to-last in pass yards allowed per game. They have allowed at least 19.7 DKFP to every starting QB they’ve faced. They’ve allowed at least one opposing WR to score at least 20 DKFP in every game. That means they’ve allowed a QB-WR stack to score over 40 combined DKFP in every single game. Two of those stacks topped 60 DKFP.

Besides the fact that the Bucs can’t stop themselves from giving up giant games, there are reasons to like Newton, Funchess and Moore independent of the matchup. Newton has scored at least 18 DKFP in every game and he has the second-best TD:INT ratio of his career. Funchess leads the team in receiving yards and receiving TDs, and he is second only to Christian McCaffrey ($7,800) in targets. Moore’s targets have either increased or remained constant every single game, and the team has shown a commitment to increasing his opportunities by incorporating him in their running game – he had two carries in Week 8 and had four carries over the six previous games. Funchess’ and Moore’s salaries are so low that managers can easily stack all three of these players with a reasonable expectation of profit.
