Five NFL teams are still perfect after Week 3 of the 2026 season: the Buffalo Bills, Kansas City Chiefs, Las Vegas Raiders, San Francisco 49ers and Minnesota Vikings. Some look like true Super Bowl threats; one owes its record to a punt return and a lot of luck. We grade each of the five — strength of the start, the eye test, and what to buy while the bandwagon still has seats.
The Five Undefeated Teams, Graded
Josh Allen and the Bills own the most complete 3-0 resume in football.
The Numbers Behind the Starts
Kansas City's new-look rushing offense keeps Mahomes and Kelce in every fourth quarter.
Who's Fading Behind Them
The chase pack tells its own story. The Los Angeles Chargers are 0-3, the only winless team in a division where two rivals are perfect. The Miami Dolphins (0-3) and Tampa Bay Buccaneers (0-3 — their worst start since 2014) are already in trouble, and Tampa Bay lost Baker Mayfield to a thumb injury late in the Minnesota loss. In the AFC East, both the Jets (narrow loss in Detroit) and Patriots (a 35-6 defeat in Jacksonville, with Drake Maye throwing two interceptions) have fallen two games behind Buffalo before October.
Two of those ugly records deserve context. New England's afternoon in Jacksonville was its worst of the season by every measure — the Jaguars scored on their opening possession, led 28-3 after three quarters, and turned Maye over twice, including a strip-sack the defense returned inside the red zone. Trevor Lawrence, meanwhile, looked like the franchise quarterback Jacksonville has been waiting for, completing 19 of 29 passes for 182 yards and three touchdowns. And in Detroit, the Jets actually moved the ball well — Geno Smith's 277 passing yards and Garrett Wilson's ten-catch afternoon were both season bests — but the Lions won the line of scrimmage with five sacks and a 4.4-yards-per-carry ground game that kept New York's offense off the field. Records this early can mislead; point differential and injury reports usually do not.
The honest read after three weeks: Buffalo and San Francisco look like the real powerhouses, Kansas City is rounding into form, Minnesota is a defense-first contender with a superstar health question, and Las Vegas is the story everyone will either mock in November or claim they saw coming. For the full weekend context — including Baltimore's 56-yard walk-off in Rio — see our Week 3 takeaways, and track every potential roster shake-up in the 2026 trade deadline watch.
Week 4: The Slate That Tests All Five
The coming weekend will do real damage to this list — it always does in late September. The headliner is Sunday in Santa Clara, where the 3-0 49ers host a Broncos team that just out-defended Matthew Stafford; one of the league's last two unbeatens from the NFC West–AFC West crossover will walk away humbled. Kansas City's divisional grind continues against an AFC West rival desperate to avoid an 0-4 hole, which makes Mahomes's visit the week's highest-leverage game for the standings.
Buffalo's path stays manageable — the kind of game where Josh Allen's supporting cast gets another week of highlight tape — while Minnesota's trip becomes a referendum on its offense without a full-strength Jefferson. Las Vegas draws the safest assignment of the five on paper, but road games in October have a way of humbling September darlings. If all five survive the weekend, this becomes one of the rarest starts in recent memory; more likely, at least one name drops off and the bandwagon pricing shifts with it. Either way, this page's verdicts get a full revision in next week's edition — and the standings table above will still tell you exactly where the jersey demand is heading.
Bandwagon Shopping Guide
Unbeaten teams sell jerseys — that is simply how football fandom works. If you are buying this week, a few pointers from our category data:
- Quarterbacks dominate early. Josh Allen jerseys are the top AFC seller right now, and Patrick Mahomes never leaves the top five nationally.
- Skill-position value picks: Rashee Rice-style buy-low windows exist every September — in Minnesota, Jordan Addison shirts are the value play while Jefferson's ankle is evaluated.
- The 49ers uniform is timeless. Scarlet-and-gold designs from the 49ers collection work whether or not the bandwagon holds.
- Family orders: the kids jerseys and women's jerseys sections carry the same 3-0 team designs in full size runs — and our 2026 buying guide covers sizing across every tier.
Key takeaways
- Five teams are 3-0: Bills, Chiefs, 49ers, Vikings, Raiders.
- Buffalo's resume is the strongest; Las Vegas's is the most surprising.
- Justin Jefferson's ankle injury is the week's defining storyline for Minnesota.
- Week 4 headliner: Broncos (3-1 after beating the Rams) visit the 49ers.
- Chargers, Dolphins and Buccaneers are all winless through three weeks.
FAQ: Unbeaten Teams, Answered
Which NFL teams are undefeated in 2026?
After Week 3, five teams remain unbeaten at 3-0: the Buffalo Bills, Kansas City Chiefs, Las Vegas Raiders, San Francisco 49ers and Minnesota Vikings.
Are the Raiders actually good this year?
The start is real — wins over the Chargers and Dolphins with a genuinely improved defense — but the next three games (New Orleans, Kansas City, New England) will decide whether Las Vegas is a playoff team or a September mirage.
What is the Vikings' biggest concern?
Justin Jefferson's ankle. He left the Week 3 win over Tampa Bay in the first quarter and was scheduled for further evaluation on Monday. Minnesota's defense has been excellent, but the offense is built around Jefferson's 13-catch, 179-yard, two-touchdown start.
Who do the Broncos play next, and why does it matter here?
Denver visits the 49ers in Week 4 — a 3-0 versus 3-1 matchup that could reshape the NFC playoff picture. It is the best game of the upcoming slate and the one most likely to shift jersey demand in both cities.
Where can I shop undefeated-team jerseys?
All five teams — Buffalo, Kansas City, Las Vegas, San Francisco and Minnesota — have full collections on Jersey Pro Guide, including player, women's and kids fits.
