The plaque gallery in Cooperstown is quiet, but the arguments to get there are loud. Every January, when the results of the latest voting cycle drop, baseball Twitter basically turns into a digital war zone. Some people think the gates are too open; others think they’re rusted shut by old guys with grudges. If you look at MLB Hall of Fame classes over the last century, you’ll see they aren't just lists of names. They’re historical snapshots of how we feel about the game's integrity, its stats, and its scandals.
Baseball is obsessed with its own history. It's the only sport where a guy who retired in 1950 is regularly compared to a guy who retired in 2020. But the way we pick the "best of the best" has changed so much it’s almost unrecognizable. We went from the "First Five" in 1936—Ty Cobb, Babe Ruth, Honus Wagner, Christy Mathewson, and Walter Johnson—to years like 2021 where the BBWAA (Baseball Writers' Association of America) looked at the ballot and collectively decided "nope," electing absolutely nobody.
The Evolution of the Voting Block
Getting into the Hall is hard. It should be. You need 75% of the vote from the BBWAA, a group of writers who have covered the game for at least ten consecutive years. For a long time, these voters were the sole gatekeepers. They valued 300 wins, 3,000 hits, and "character." But character is a messy metric.
In the early days, MLB Hall of Fame classes were massive because they were playing catch-up. Think about it. In 1936, they had fifty years of legends to sort through. After that initial burst, things slowed down. Then came the era of the Veterans Committee—now technically broken into various "Era Committees"—which serves as a safety net for players the writers missed.
The Math Nerd Takeover
Recently, the vibe shifted. Hard. We moved from "he looks like a Hall of Famer" to "his JAWS score is 3.4 points above the average CF inductee." Analytics changed the way these classes are built. Players like Scott Rolen or Todd Helton might not have been first-ballot locks twenty years ago because their raw totals didn't scream "immortality." But today, voters look at park-adjusted stats and defensive metrics. They see the value that was hidden in plain sight. It's why the 2024 class, featuring Adrián Beltré, Joe Mauer, and Todd Helton, felt like a victory for the "new school" of baseball thought. Beltré was a no-brainer because he checked both boxes: 3,000 hits and elite advanced metrics.
The Elephant in the Room: PEDs and the "Shutout" Years
You can't talk about MLB Hall of Fame classes without talking about the guys who aren't in them. Barry Bonds. Roger Clemens. Sammy Sosa. Alex Rodriguez. These are some of the greatest players to ever touch a diamond, yet they remain stuck in a sort of purgatory.

The 2013 ballot was a total disaster. It was the first year Bonds and Clemens were eligible, and the writers sent a clear message: "Not yet, and maybe not ever." That year, nobody was elected. Not one person. It was a protest vote. Fans were furious. The Hall of Fame eventually shortened the window of eligibility from 15 years down to 10, largely to stop these debates from dragging on for two decades.
Is the "Morality Play" Ending?
Honestly, the morality stuff is exhausting. We already have players in the Hall who were, let’s be real, pretty terrible human beings. Ty Cobb wasn’t exactly a saint. But the steroid era feels personal to the writers who covered it. They feel lied to. However, we're seeing a slight thaw. Gary Sheffield got 63.9% in his final year on the ballot in 2024. That’s not 75%, but it shows that the hardline stance is softening as younger voters enter the pool.
The Era Committees have also become the "back door" for controversial figures. While the writers might say no, these smaller committees—made up of former players and executives—sometimes have a different perspective. They recently put in Fred McGriff and Gil Hodges, two guys who waited forever but finally got their moment.
Breaking Down the "Unanimous" Barrier
For the longest time, the "unanimous" inductee was a myth. A ghost. Even Babe Ruth didn't get 100% of the vote. Some writer, somewhere, always thought, "Well, if Cy Young didn't get 100%, nobody should." It was a weird, petty tradition.
Then came 2019.

Mariano Rivera shattered the ceiling. The greatest closer of all time became the first player to ever appear on every single ballot. 425 out of 425. It changed the energy around how we view MLB Hall of Fame classes. It proved that it's okay to agree. Derek Jeter came incredibly close the following year, missing by just one solitary vote. Somewhere, a writer is probably still hiding from Yankees fans because of that "no" vote.
Why Small Classes Matter
There's a school of thought that "small is better." In 2022, David Ortiz was the only player elected by the writers. Some fans hate that. They want a big party in July with five or six legends on the stage. But a solo induction makes the spotlight much brighter. When "Big Papi" went in alone, the entire weekend became a celebration of Dominican baseball and his specific legacy in Boston. It felt weighty.
What Most People Get Wrong About the Process
People think the Hall of Fame is a museum run by MLB. It’s not. It’s an independent non-profit. This is a huge distinction. MLB doesn't get to decide who gets a plaque. They can't force the writers to put Pete Rose in.
Also, the "First Ballot" thing? It’s kind of a manufactured status symbol. Getting in on the first try is cool, but a plaque in the tenth year is made of the same bronze. Just ask Tim Raines or Duke Snider. Raines languished for years because his stats (stolen bases and on-base percentage) weren't appreciated until the analytics revolution caught up to him in his final year of eligibility.
The Coors Field Bias
For years, players from the Colorado Rockies were penalized. "It's just the thin air," people said. Larry Walker broke that curse in 2020. His induction was a massive turning point for MLB Hall of Fame classes because it proved that voters were finally looking at "neutralized" stats. They realized that even if the ball flies further in Denver, you still have to be a world-class athlete to hit it. This paved the way for Todd Helton and will eventually help guys like Nolan Arenado.

How to Track Future Classes
If you want to understand where the Hall is going, you have to watch the "trackers." Ryan Thibodaux’s Hall of Fame Ballot Tracker is basically the Bible for this stuff. Every December, he collects public ballots, and we get a preview of who’s trending up.
The "Climb" is Real:
- Year 1: Player gets 20%. People start talking.
- Year 4: Player hits 45%. The "advanced stats" crowd starts writing articles.
- Year 8: Player hits 65%. It becomes a national debate.
- Year 10: The "Final Year" bump. Usually, if a guy is close, the writers push him over the edge out of respect for his last chance.
Look at Billy Wagner. The lefty closer has been slowly clawing his way up. He’s the perfect example of how modern classes are built—one percentage point at a time, through years of advocacy and statistical re-evaluation.
Actionable Steps for the Baseball Fan
If you really want to dive into the world of Cooperstown, don't just look at the home run totals.
- Check the JAWS score: Use Baseball-Reference to look up a player's JAWS (Jaffe Academic War Score). It compares a player to the average Hall of Famer at their position. If they are above the line, they usually belong.
- Follow the "10-Year Rule": If a player you love is in year 7 or 8 and is hovering around 50%, that’s when you need to start paying attention. That's when the momentum usually shifts.
- Visit in the "Off-Season": Don't go to Cooperstown during Induction Weekend in July unless you like crowds of 50,000 people. Go in October. The town is empty, the leaves are changing, and you can actually stand in front of the plaques and read the stories.
- Distinguish between "Famous" and "Great": The Hall isn't the "Hall of Very Good." Being a fan favorite doesn't get you a plaque. Understanding the difference between a high peak (like Johan Santana) and long-term longevity (like Bert Blyleven) is key to predicting who makes the cut.
The Hall of Fame is an imperfect institution because it’s run by humans. It’s biased, it’s slow to change, and it’s prone to drama. But that’s exactly why we can’t stop talking about it. Every new class is an opportunity to redefine what greatness looks like in the context of the American pastime. Whether you're a "small hall" purist or you want everyone with 400 homers in, the debate is the point. It keeps the legends alive long after they’ve stopped swinging the bat.
