The NFL is back — and while preseason box scores don't count in fantasy leagues, the information hidden inside them absolutely does.
The first full night of the 2026 NFL preseason delivered six games Thursday, and there was plenty for fantasy managers to digest. Starters were used sparingly, several veterans never saw the field, and some of the most important developments came from rookies and players fighting for roster spots.
The biggest lesson from Thursday: don't chase the box score. Chase the usage.
Here's what actually mattered.
Raiders 14, Cardinals 27: Fernando Mendoza Makes His Debut
The most fantasy-relevant quarterback story of the night came from Las Vegas.
Fernando Mendoza, the No. 1 overall pick and 2025 Heisman Trophy winner, completed 10 of 16 passes for 97 yards and a touchdown in his NFL debut. He played four drives and looked comfortable enough to immediately put himself into the fantasy conversation.
Veteran Kirk Cousins also opened the game efficiently for Las Vegas, throwing a touchdown on his opening drive.
That quarterback competition is now worth watching closely.
The Cardinals also received a major glimpse of rookie running back Jeremiyah Love, who rushed for 58 yards. Arizona rookie quarterback Carson Beck did not play because of injury.
Fantasy impact
Mendoza: Stock up for dynasty and Superflex formats. Don't draft him as though Thursday proved he's already a fantasy star, but the debut was encouraging.
Love: One of the night's most intriguing rookie developments. His explosiveness and opportunity make him a player to monitor aggressively during the remaining preseason games.
Cousins: His presence creates an important complication for Mendoza's immediate redraft value.
The takeaway isn't "draft Mendoza tomorrow." It's keep watching this quarterback battle.
Steelers 28, Packers 9: Pittsburgh's Quarterback Depth Gets Interesting
Pittsburgh's backups stole the show.
The Steelers' backup quarterbacks combined for 313 passing yards and two touchdowns, with rookie Drew Allar leading an impressive passing performance.
Meanwhile, Green Bay's offense struggled badly after its starters departed. Jordan Love played only briefly, and the Packers finished with just 97 passing yards among their four quarterbacks.
The Steelers' victory eventually became a rout once Green Bay turned to its deepest reserves.
One of the more interesting fantasy developments came from Pittsburgh rookie receiver Germie Bernard, who reportedly played extensively with the first-team offense and made a strong case for a significant role.
Green Bay's receiver deployment was also noteworthy. Matthew Golden received first-team work, while Jayden Reed's usage raised questions about how Green Bay will distribute its personnel in different formations.
Fantasy impact
Germie Bernard: One of the night's biggest dynasty winners.
Matthew Golden: Continue paying attention. First-team deployment matters considerably more than a preseason touchdown.
Jayden Reed: Thursday's usage is something fantasy managers should monitor rather than overreact to.
Drew Allar: Dynasty managers should put his name on the watch list.
Bengals 16, Lions 14: Joe Burrow Gets a Look, Rookie Tight End Scores
Cincinnati escaped with a 16-14 victory over Detroit.
Joe Burrow saw limited action, while veteran Joe Flacco handled quarterback duties and threw a touchdown to rookie tight end Jack Endries.
For fantasy purposes, the important part wasn't the final score.
It was seeing Burrow on the field and watching Cincinnati begin working through its depth.
The Lions' offense produced only 14 points, with Jake Bates supplying a field goal and the offense otherwise struggling to generate much consistency.
Fantasy impact
Burrow: Nothing Thursday should change his fantasy draft position.
Endries: The touchdown is worth noting, but don't let one preseason score turn him into a draft target. Watch his route participation and involvement with the second unit.
Lions receivers: No reason for fantasy managers to panic based on a preseason opener with limited starters.
Colts 13, Patriots 13: Richardson Shows the Good and the Bad
This was arguably the most fascinating quarterback performance of the night.
Anthony Richardson ran for a touchdown but also committed two turnovers as Indianapolis and New England finished in a 13-13 tie.
Richardson's rushing ability remains the fantasy cheat code that makes him so intriguing. But Thursday also provided another reminder of the risk attached to his fantasy profile.
New England rested Drake Maye, while Tommy DeVito completed 13 of 22 passes for 138 yards and a touchdown.
Running back Jam Miller led New England with 55 rushing yards on 14 carries, while Lan Larison made an impact in the passing game.
Fantasy impact
Richardson: Still one of fantasy football's highest-upside quarterbacks. The turnovers don't erase the rushing production.
Jam Miller: Worth monitoring as a potential deeper-league name.
Lan Larison: Another Patriots backfield player to track as the competition develops.
Drake Maye: Nothing about Thursday changes his fantasy outlook because he didn't play.
Chargers 27, Texans 7: Amar Johnson Announces Himself
This may have been the most fantasy-friendly running back performance of the night.
Amar Johnson scored two rushing touchdowns for Los Angeles and added a 55-yard reception before scoring another rushing touchdown later in the game.
The Chargers eventually cruised to a 27-7 victory.
Houston got a touchdown from Jared Wayne after a 31-yard gain from rookie tight end Marlin Klein, but the Texans' offense struggled after its opening possession.
Houston quarterback Davis Mills finished with 82 passing yards, one touchdown and a fumble.
Fantasy impact
Amar Johnson: 🚨 One of the biggest preseason stock risers.
Preseason production must be treated carefully, but explosive plays plus touchdown production plus receiving involvement is exactly what fantasy managers want to see from a young running back.
Marlin Klein: Put him on the dynasty watch list.
Davis Mills: More relevant to Houston's depth chart than standard fantasy drafts at this point.
Titans 19, 49ers 13: Cam Ward's First Look Comes With a Warning
Tennessee's Joey Slye stole the statistical spotlight, drilling four field goals — including three from beyond 50 yards.
But fantasy managers were watching the quarterback position.
Cam Ward got valuable preseason work against San Francisco, while the 49ers rested Brock Purdy.
San Francisco's rookie quarterback Kurtis Rourke was particularly impressive before leaving with a rib injury. Rourke completed 12 of 14 passes for 101 yards and added 14 rushing yards before exiting.
The injury obviously makes his status something to monitor.
Fantasy impact
Cam Ward: The first preseason game doesn't dramatically alter his draft value, but his development is extremely important for Tennessee's offense.
Kurtis Rourke: The performance was excellent before the injury. His health now becomes the story.
De'Zhaun Stribling: One of the more intriguing rookie wide receivers to emerge Thursday. His athletic ability and playmaking generated considerable attention.
Thursday's Biggest Fantasy Winners
📈 Stock Up
Amar Johnson — Chargers RB
The combination of rushing touchdowns and receiving explosiveness makes him one of the players fantasy managers should investigate immediately.
Fernando Mendoza — Raiders QB
A composed debut from the No. 1 overall pick keeps his dynasty/Superflex appeal moving in the right direction.
Germie Bernard — Steelers WR
First-team usage is the important part here. The preseason box score is secondary.
Jeremiyah Love — Cardinals RB
The rookie's explosiveness deserves attention as Arizona continues sorting out its backfield.
De'Zhaun Stribling — 49ers WR
A name that deserves to move onto deeper dynasty watch lists.
📉 Stock Down / Questions
Jayden Reed — Packers WR
Not because he had a bad preseason game, but because Green Bay's personnel usage deserves monitoring.
Anthony Richardson — Colts QB
The rushing touchdown is exactly what fantasy managers want. The two turnovers are exactly what makes him volatile.
Kurtis Rourke — 49ers QB
The performance was encouraging; the rib injury makes his next update much more important.
The Fantasy Lesson From Night One
The easiest mistake to make during preseason is chasing touchdowns.
Don't.
A fourth-string running back scoring twice against players who won't make the roster tells us very little.
A rookie receiver playing with the first-team offense tells us much more.
A running back receiving targets tells us more than a 60-yard touchdown against backups.
A quarterback's number of first-team drives matters more than his final passer rating.
That's how fantasy managers should read preseason.
Usage > production.
Thursday gave us six games and a bunch of data points. Some will disappear by September. Others could eventually become the difference between winning and losing a fantasy league.
And that's why the preseason matters.
