10 fantasy data points you need to know for Week 4

This week four data dump episode has Matt Harmon and Ray Garman running through ten stat-driven storylines for fantasy managers, from Ashton Jeanty's efficiency concerns to Zay Flowers' historic route efficiency, before closing with a league-recap segment. The overarching thread is that three weeks in, the elite superstars are performing as expected, but the real signal is in the mid-round wide receivers and backfield timeshares where usage data is starting to diverge sharply from preseason assumptions.

The arguments

Ashton Jeanty's volume is masking a real efficiency problem tied to a lingering ankle issue. Garman laid out Jeanty's decline from 4.4 to 2.3 to 2.9 yards per carry across three weeks, zero rushing touchdowns, and a brutal 34.1% success rate, then noted Jeanty was seen getting his ankle taped on the sideline after Week 3. Both hosts agreed he's not droppable given 20+ opportunities a game, but Harmon flagged that if backup Mike Washington — who looked visibly more explosive in relief — starts stealing 8-10 touches, it caps Jeanty's ceiling; Garman said he wouldn't call Jeanty untouchable in trade talks.

Zay Flowers is the most efficient receiver in football when healthy, and both hosts now rank him inside their top five to seven rest-of-season receivers. Harmon cited Flowers' 9.36 yards per route run (more than double the next closest qualifying receiver) and a 44% first-down rate, driven by Lamar Jackson's tendency to hyper-target his WR1 rather than distribute to Rashod Bateman. Garman pushed Harmon to consider ranking Flowers even higher, with both ultimately settling on a range of five to seven, behind only Chase, JSN, St. Brown, Lamb and maybe Olave or a healthy London.

Garrett Wilson is finally delivering the true WR1 season the community has waited five years for, powered by Geno Smith's efficient play. Harmon and Garman pointed to Wilson's 36% target share, Geno Smith's league-leading 76% completion rate, and Wilson's seventh-highest overall usage score among receivers as evidence this isn't a mirage. Garman added that Kenyon Sadiq (fresh off seven catches, 105 yards, a touchdown, and only 20% rostered) is riding the same concentrated-target wave since Braylon Allen isn't a receiving threat and AD Mitchell and Mason Taylor are banged up.

Brock Purdy is a locked-in weekly QB1 and arguably the third-best fantasy quarterback behind only Josh Allen and Lamar Jackson. Garman highlighted back-to-back top adjusted net-yards-per-attempt games and a 300-yard, four-touchdown performance on just 15 completions, calling Kyle Shanahan's scheme unmatched even amid injuries to Mike Evans and Ricky Pearsall. Harmon flagged tougher tests against Denver and Seattle in Weeks 4-5 as the real litmus test, but both agreed he's a start-every-week option, with Harmon floating the idea San Francisco could pursue a midseason receiver trade given the injury attrition.

Kyron Williams' receiving role has quietly become one of the most unique pass-catching profiles at running back. Garman noted Williams outgained Jahmyr Gibbs and Christian McCaffrey in receiving yards in Week 3, and Harmon confirmed via air-yards data that Williams' 4.92 air yards per target dwarfs every other running back with double-digit targets. Harmon somewhat surprisingly said he'd rather roster Williams than Jeanty right now given how the Rams have failed to funnel any similar receiving work to backup Blake Corum.

Neither host trusts the Eagles' offense to look meaningfully different from prior seasons, and Jalen Hurts remains schematically capped. Harmon's data showed Philadelphia dead last in play-action rate and 30th in motion rate — nearly identical to last year despite offseason promises of change — with Hurts' passes skewing heavily to short-right and almost nothing to the deep or short-middle. Garman was particularly critical of how Kaimi Lemon is being deployed on low-value screens behind the line rather than as a downfield weapon, while agreeing the passing game could still improve modestly even if the run game stays broken.

What it means for your roster

• Hold Jeanty, but monitor Mike Washington closely — Washington sits at just 34% rostered and both hosts want him firmly on your bench as insurance in case the ankle issue lingers or the committee shifts.
• Zay Flowers should be treated as a top-five-to-seven rest-of-season receiver — start him with confidence in any matchup once healthy; both hosts see him outproducing his current market perception.
• Prioritize Kenyon Sadiq off waivers this week — Harmon said he's ranking Sadiq over previously higher-drafted tight ends like Tucker Kraft and Colson Loveland for Week 4.
• Garrett Wilson is a weekly WR1 start, not just a matchup play — both hosts believe the fantasy community still hasn't priced in how concentrated and competent this Jets passing game has become.
• Consider Kyron Williams as a top-12 running back and even preferable to Jeanty in some formats — his receiving usage is unusually valuable and Blake Corum isn't cutting into that role.
• Brock Purdy is a lock-and-load starting quarterback, but watch his next two matchups (Denver, Seattle) before fully trusting the volume of easy production continues.
• Don't overreact to one big Eagles offensive week — the underlying play-calling data suggests continued middling weekly ceilings for Hurts and the Philadelphia skill players until something structurally changes.
