NFL Week 10 DFS Main Slate Strategy: 49ers at Cowboys Is the Stack, Kaleb Johnson Is the Value and Seattle's Defense Draws a Rookie

The San Francisco 49ers at Dallas Cowboys game is the center of Week 10's main DFS slate. Dimers listed San Francisco as a 3.5-point favorite with a total of 55.5, well above every other 1 p.m. or 4 p.m. ET game. The rest of the slate is shaped by injuries. Puka Nacua is out for an extended stretch (the Rams are keeping him off injured reserve), Josh Jacobs is out after finger surgery, and several teams are starting quarterbacks who were not the plan in August.

This breakdown covers the ten games in the 1 p.m. and 4 p.m. ET windows. Sites differ on whether the 9:30 a.m. ET Patriots and Lions game in Munich is part of the main slate, so check your contest lobby. Salaries are discussed in tiers rather than exact prices. The Bears, Eagles, Buccaneers and Broncos are on bye.

Stats Insider listed the Rams as 7.5-point favorites at Arizona. Totals for the remaining games were not consistent enough across sources to list.

Stack 1: 49ers at Cowboys

The highest total on the slate gets the most popular stacks, and it deserves them. Christian McCaffrey is the foundation. He was cleared for Week 9 and the 49ers beat Las Vegas 38-17, and with Mike Evans (Achilles tendinitis) expected to sit again and Deebo Samuel uncertain with a hamstring strain, San Francisco's offense runs through him even more than usual. A 4:25 p.m. ET kickoff also gives you the inactive list before you commit.

Brock Purdy paired with McCaffrey and newly acquired Keenan Allen is the standard build. Allen is in the cheap tier after a sixth-round-pick trade from Indianapolis, and he gives Purdy a reliable option on third downs. On the other side, Dak Prescott is the bring-back. Dallas just beat Indianapolis 27-23, and a close game with a 55.5 total gives Prescott a 300-yard path. If you expect Dallas to pass more than usual because San Francisco is favored, build around a Prescott stack with McCaffrey as the bring-back instead.

Stack 2: Bills at Jets, and a Chiefs pivot

Josh Allen at the Jets is the safest high-priced quarterback. Buffalo is favored by more than a touchdown in a game Dimers totaled at 51, and Allen's rushing gives him a floor no other quarterback on the slate can match. The catch: the Bills played Monday night in Minnesota, so they are on a short week. Buffalo's defense is also in play against a Jets offense that just scored 12 points against Kansas City.

The lower-owned pivot is Kansas City at Atlanta. The Falcons traded safety Jessie Bates III to Jacksonville at the deadline and gave up 155 receiving yards to Ja'Marr Chase in Madrid. Patrick Mahomes was hurt in Week 9 with an elbow injury, which will keep some players off him, but he was a full participant in Wednesday's practice. A Mahomes stack with Josh Downs at a low salary is a strong tournament build. Downs has only three practices with his new team, so do not rely on him in cash games. Bijan Robinson, who ran for 100 yards and a touchdown against Cincinnati, is the natural bring-back.

Value plays by position

Quarterback: Tyler Shough, Saints, vs. Carolina. Shough threw for 265 yards and ran for 51 in an overtime win over Cleveland, and Carolina allowed 27 and 43 points in the two games before Week 9. He is in the low salary tier, and his rushing gives him upside most cheap quarterbacks lack. Stacking him with Juwan Johnson, who caught his game-winning overtime touchdown, is a cheap correlated pair.

Running back: Kaleb Johnson, Packers, vs. Minnesota. Johnson is the slate's most important value with Jacobs out. He ran 14 times for 68 yards and a touchdown after Jacobs got hurt, and a near-minimum running back with a lead role frees salary for McCaffrey or Allen. Audric Estime (15 carries, 72 yards and a touchdown in Week 9) is a deeper value in the same Saints game.

Wide receiver: Keenan Allen and Josh Downs. Both are new to their teams, and both are cheap, so their salaries reflect their old roles. Allen is the safer one this week because the 49ers have fewer healthy receivers. Tank Dell at Cleveland is another mid-priced option after scoring in Houston's five-touchdown passing game against the Chargers.

Tight end: Harold Fannin Jr., Browns, vs. Houston. Deshaun Watson is expected to return, according to ESPN, and Fannin caught 10 passes for 154 yards in Watson's last start. He then scored a 39-yard overtime touchdown with Shedeur Sanders. His salary may not reflect a top-10 tight end role yet.

Defenses

Seattle at Las Vegas is the top defense play. Fernando Mendoza makes his first NFL start against a defense that just held Arizona to three points. Rookie quarterbacks facing a strong pass rush for the first time usually take sacks and throw interceptions.

Jacksonville at Tennessee is the safe option, with the Jaguars favored by about 10 points on the road. Buffalo at the Jets is the third choice. If you need a cheap defense, Baltimore on Monday is not on the main slate, so look at Indianapolis at home against a Miami team that has struggled to score.

The Verdexed angle

This slate has one clear shootout and many games with uncertain quarterbacks or injury news. In GPPs, the ownership edge comes from those uncertain games. Mahomes and Fannin are likely to be owned less than their roles justify, because the injury and quarterback news around them scared off some players early in the week. In cash games, use the confirmed roles: McCaffrey, Josh Allen, Shough and Kaleb Johnson.

Late swap and what's next

The Packers' and Chiefs' situations will decide many lineups. Leave a late-swap spot open for the 4 p.m. ET games: San Francisco's receiver statuses and the Seahawks' quarterback plan will be confirmed when inactives are posted about 90 minutes before kickoff. Rams pass catchers lose their best option with Nacua out and Davante Adams still on injured reserve, so the Rams at Arizona game is a place to be underweight rather than to chase a thin receiver room.
