Everyone has an opinion. You sit at a bar, mention "the best," and suddenly three people are yelling about rings while someone else is pulling up a spreadsheet of adjusted net yards per attempt. Comparing a guy who played in the 1950s to a modern-day cyborg like Patrick Mahomes is basically impossible. But we do it anyway.
Football has changed so much. Back in the day, defensive backs could basically clothesline a receiver without getting a flag. Now, if you look at a quarterback the wrong way, it’s fifteen yards and a first down. That makes the greatest NFL QBs of all time discussion a moving target.
The Unmatchable Resume of Tom Brady
Honestly, it’s hard to start anywhere else. Seven rings. That’s more than any single NFL franchise has in its entire history. People used to say he was a "system quarterback" or that Bill Belichick was the real genius. Then he went to Tampa Bay at 43 years old and won another one just to prove a point.
Statistically, the numbers are just stupid. He’s the leader in passing yards ($89,214$), touchdowns ($649$), and completions ($7,753$). But it wasn't just the volume. It was the fact that he stayed at the top for over two decades. Most players are lucky to survive five years in the league; Brady was still an MVP candidate when he was old enough to be his teammates' dad.
The "clutch" factor with Brady was different. You knew, deep down, that if he had the ball with two minutes left and was down by four, your team was probably toast. Just ask the Falcons. That 28-3 comeback in Super Bowl LI wasn't just a game; it was a psychological trauma for an entire city.
Joe Montana and the Art of Perfection
Before Brady, there was "Joe Cool." Montana was the guy you wanted if the game was on the line and you needed a calm hand. He went 4-0 in Super Bowls. Not a single interception in any of them. Think about that for a second. On the biggest stage in sports, against the best defenses of the 80s, he never threw the ball to the other team.

The connection he had with Jerry Rice was legendary, but people forget he won two rings before Rice even got to the league. He was the master of Bill Walsh’s West Coast Offense. It was all about precision and timing. While Brady won with longevity, Montana won with a peak that felt untouchable.
Peyton Manning: The On-Field Coordinator
If Brady was the ultimate winner and Montana was the ultimate performer, Peyton Manning was the ultimate mind. Watching Peyton at the line of scrimmage was like watching a grandmaster play chess against a bunch of kids. He’d be waving his arms, yelling "Omaha," and changing the play based on a safety’s foot placement.
Manning’s 2013 season with the Denver Broncos is still the gold standard for statistical dominance. 55 touchdowns. 5,477 yards. He won five MVPs with two different teams. The knock on him was always the postseason—he "only" won two rings and had a few more "one-and-done" playoff exits than fans liked. But in terms of pure quarterbacking ability, he basically reinvented how the position is played.
Why the Modern Era Is Different
Now we have Patrick Mahomes. It feels a little early to put a 30-year-old in the GOAT conversation, but look at what he’s doing. By the start of 2026, he’s already chasing the all-time greats with three rings and multiple MVPs. He does things with his body that shouldn't be physically possible—no-look passes, left-handed throws under pressure, and scrambles that make defenders look like they're on skates.
It’s a different game now. The league wants points. They want highlight reels. Mahomes is the perfect product of that, but he also has the substance to back it up.

The "What If" Kings: Marino and Rodgers
We have to talk about Dan Marino. If you put 1984 Dan Marino in a time machine and dropped him into 2026, he’d probably throw for 6,000 yards. He threw 48 touchdowns in an era where 25 was considered elite. He never won a Super Bowl, which is why he usually sits at the bottom of these top-five lists, but his pure arm talent was arguably the best we’ve ever seen.
Then there's Aaron Rodgers. For a long time, he was the efficiency king. His touchdown-to-interception ratio is something like a 4-to-1 spread. He makes the hardest throws in the world look like he's playing catch in the backyard. Even now, playing for the Steelers in 2026 at age 42, he's still finding ways to be effective by playing "mistake-free" ball. But like Marino, the lack of multiple rings (he only has the one from the 2010 season) keeps him in a different tier than Brady or Montana for most voters.
The Old Guard Nobody Remembers
We can’t just ignore the guys who built the league. Johnny Unitas. Otto Graham.
Unitas was the first modern quarterback. He had the high-top boots and the crew cut, and he called his own plays. He held the record for consecutive games with a touchdown pass for 52 years until Drew Brees finally broke it in 2012.
Otto Graham is the one people really sleep on. He played ten seasons for the Cleveland Browns and made the championship game in all ten of them. He won seven titles (four in the AAFC, three in the NFL). Sure, the league was smaller and the competition was different, but winning at a 70% clip for a decade is insane regardless of the era.

How Do We Actually Rank Them?
There’s no perfect formula. If you value winning above all else, Brady is #1 and it’s not close. If you value peak performance and perfection, you might lean Montana. If you want the smartest guy to ever touch a football, it’s Manning.
Most experts today seem to settle on a top-five that looks something like this:
- Tom Brady (The longevity and the rings)
- Joe Montana (The 4-0 Super Bowl record)
- Peyton Manning (The regular season god)
- Patrick Mahomes (The highest ceiling we've ever seen)
- Johnny Unitas or Otto Graham (The pioneers)
There’s a lot of nuance here. You have to consider the rules of the time, the quality of the teammates, and even the coaching. Brady had Belichick. Montana had Walsh. Mahomes has Andy Reid. It’s rare to see a truly great QB win it all with a mediocre coach.
Actionable Insights for Fans and Debaters:
- Look past the rings: Championships are a team stat. While they matter for legacy, they don't always tell you who the better "player" was. (See: Marino vs. Trent Dilfer).
- Contextualize stats: Don't compare a 4,000-yard season in 1978 to one in 2024. Use "Era Adjusted" stats like those found on Pro-Football-Reference to see how a player performed relative to their peers.
- Watch the tape: Stats don't show the "escapability" of Fran Tarkenton or the "Sheriff" command of Manning at the line. Highlights matter for understanding the "how" behind the numbers.
- Stay updated on Mahomes: He is the only active player with a realistic shot at the #1 spot. Keep track of his pace compared to Brady’s first ten seasons to see if the trajectory holds.
The debate over the greatest NFL QBs of all time will never be settled, and that’s basically the point of being a sports fan. It’s about the arguments as much as the games.
