NEW ORLEANS — Three years have passed since Deion Sanders, arguably the greatest cornerback in NFL history, complained loudly about the Pro Football Hall of Fame lowering the bar for enshrinement.

Were too many borderline candidates making it through the process, watering down what it meant to earn the coveted gold jacket and bronze bust in Canton? Sanders clearly thought so. The Hall agreed, implementing stricter rules in August 2024 to, in its words, “help ensure that membership in the Hall of Fame remains elite.”

Fans will see the results of the new rules for the first time when the Hall reveals its 2025 class Thursday night at the NFL Honors show in New Orleans, site of Super Bowl LIX. As one of the 49 selectors, I participated in the voting but do not know the results.

Here’s a primer on what to know and expect heading into the announcement:

1. Sanders had a point: The Hall was indeed enshrining candidates at a higher rate recently.

The Hall welcomed 179 new members from 2000 to ’24, up from 118 over the previous 25-year period (1975-99). That included a special 20-member NFL Centennial class in 2020.

The selection committee has enshrined the maximum five modern-era candidates per year for 17 consecutive years. The average was 4.1 per year over the preceding 40-year period.

The swell in numbers also reflects the Hall’s decision to separate coaches and contributors from modern-era candidates beginning in 2015. The committee has enshrined 17 coaches and contributors in the nine years since, in addition to the five-person modern-era classes.

As a result, the Hall has enshrined 7.8 total candidates per year on average since 2015, not counting the 20-member Centennial class.

“With the revisions, classes are more likely, statistically, to include five or six members,” the Hall said in a news release announcing changes to the process.

2. Sanders had another point: Less-accomplished candidates had indeed become more likely to earn enshrinement, at least by one measure.

Bruce Smith, Rod Woodson, Randall McDaniel and Derrick Thomas were the modern-era players enshrined in 2009. Jerry Rice, Emmitt, Smith, John Randle, Russ Grimm and Rickey Jackson followed in 2010.

These super-elite classes rank 1-2 since 1980 on average using Pro Football Reference’s Hall of Fame Monitor, which adjusts for era and position when taking into account career production and honors to predict the likelihood of being enshrined (the data is available for players who debuted since 1955).

The third-ranked class since 1980 featured Walter Payton, Larry Little and Dan Fouts in 1993. Barry Sanders and John Elway headlined the fourth-ranked class in 2004 (Carl Eller also was part of it). The fifth-ranked class by this measure featured Ray Lewis, Randy Moss, Terrell Owens, Brian Urlacher and Brian Dawkins (2018). The 2000 class was next with Ronnie Lott, Joe Montana and Howie Long.

At the other extreme, the 2022 modern-era class of Sam Mills, Richard Seymour, Bryant Young, LeRoy Butler and Tony Boselli ranked 44th out of 45 classes since 1980. Only the 1996 class (Charlie Joiner, Mel Renfro, Dan Dierdorf) ranked lower.

The average class quality (using a five-year rolling average of the Hall of Fame Monitor metric) peaked in 2011 and remained relatively steady until the past three years. In 2024, it dropped to its lowest level since 2003.

While there is no comprehensive metric for determining Hall worthiness, when every member of a class might have missed the cut in a strong year, alarms sound. Sanders did not need help from Pro Football Reference to feel what those numbers suggest was happening.

Did Sanders and the Hall overreact to a single outlier class? Was it time to reverse the trend toward larger classes? The Hall decided to err on the side of exclusivity while its ranks remain proportionally more exclusive than other halls of fame (there are 378 members of the Hall at present, compared to 351 for the Baseball Hall of Fame and “more than 450” for the Naismith Memorial Basketball Hall of Fame, despite the NFL having employed many more players).

3. Here’s how the 2025 class compares.

The 15 modern-era finalists this year are cornerback Eric Allen, defensive end Jared Allen, tackle Willie Anderson, guard Jahri Evans, tight end Antonio Gates, receiver Torry Holt, linebacker Luke Kuechly, quarterback Eli Manning, receiver Steve Smith, outside linebacker Terrell Suggs, running back Fred Taylor, kicker Adam Vinatieri, receiver Reggie Wayne, safety Darren Woodson and guard Marshal Yanda.

Vinatieri and Manning are two of the more interesting candidates this year. Both delivered in the clutch during Super Bowls. Both also enjoyed long careers. But Vinatieri is a kicker competing against every-down players, while Manning arguably was never a top-five player at his position.

Both rank higher on the Pro Football Reference Hall of Fame Monitor than some others at their positions who are already enshrined.

The table below ranks these finalists by their Hall of Fame Monitor scores (logos reflect the teams with which each played the most games).

In general, a score around 100 suggests likely enshrinement. But dozens of Hall of Famers have scores in the 40-80 range, including decorated quarterbacks such as Joe Namath (70.0), Troy Aikman (64.3) and Jim Kelly (59.1).

If the five finalists with the highest Hall of Fame Monitor scores were enshrined this year, the 2025 class would average 111.2, which would rank 18th among the 45 classes since 1980. But for the first time in nearly two decades, there might not be five modern-era inductees.

4. No fewer than three and no more than five modern-era finalists will be enshrined this year. The chances for a five-man class are diminished under new rules.

In past years, the selection committee — which typically comprises 50 voters but currently has one open spot — chose five finalists from the 15. Once this reduction was made, each of the remaining five needed 80 percent “yes” votes from the committee to gain enshrinement. Under this setup, the final five gained enshrinement every time for the past 17 years.

Under new rules, the final 15 are reduced to seven. At that point, each voter picks five of the seven. Candidates receiving 80 percent of the votes gain enshrinement.

The new math makes it possible for none of the final seven to meet the 80 percent cutoff (40 of 49 votes). If fewer than three meet that percentage, as in the first hypothetical scenario shown below, the three with the most votes will gain enshrinement (we’ll detail tiebreaking procedures separately).

For the maximum five modern-era candidates to be selected, the other two finalists could command no more than 45 combined votes (or 50 in a typical year with 50 voters). Such a scenario might look something like this.

5. The five senior/coach/contributor finalists compete against each other, not against the modern-era finalists.

Voters are not forced to choose between the modern-era finalists listed above and the following senior/coach/contributor finalists: seniors linebacker Maxie Baughan, receiver Sterling Sharpe and offensive tackle Jim Tyrer, who have all been retired for at least 25 years; former Green Bay and Seattle coach Mike Holmgren; and former NFL co-founder Ralph Hay, the contributor.

Bill Belichick becomes eligible in the coach category next year if he does not return to the NFL by then. That raises the possibility of Belichick advancing as the coach candidate to compete for votes with Patriots owner Robert Kraft, who could emerge in the contributor category.

6. Between one and three senior/coach contributor finalists will be enshrined. Their chances for enshrinement are diminished under new rules.

In past years, finalists from these categories gained enshrinement if each received 80 percent approval from the committee. Their odds for enshrinement were high because voters did not have to choose these candidates at the expense of any others. Voters could simply vote “yes” without consequence, essentially rubber-stamping candidates put forth by the various subcommittees.

Under new rules, voters must pick three of five candidates from these categories. Only those receiving 80 percent of the votes gain enshrinement. If no finalist meets that bar, the single finalist with the most votes gains enshrinement.

As a hypothetical (see below), if one candidate gets 42 of 49 votes (86 percent) and another gets 37 of 49 votes (76 percent), only the first candidate would gain enshrinement, and only 68 votes would remain for the other three candidates.

For the maximum three candidates from this category to be selected, the other two candidates could command no more than 27 combined votes (or 30 in a typical year with 50 voters).

7. The eighth tiebreaking procedure would favor Marshal Yanda over all other 2025 candidates, but don’t worry — it won’t come to that.

What happens if fewer than three modern-era finalists and/or zero senior/coach/contributor finalists receive 80 percent of the votes? The Hall would then determine candidates based on the following eight criteria, in this order:

• Most votes for election (final ballot), including the vote for each senior, coach or contributor candidate;

• Most votes in the vote to reduce from 10 to seven modern-era player finalists;

• Most votes in the vote to reduce from 15 to 10 modern-era player finalists;

• Most votes to reduce from 25 to 15 modern-era player semifinalists;

• Most votes to reduce from the final preliminary list to 25 modern-era player semifinalists;

• Most times as a finalist;

• Most times on the preliminary list;

• Alphabetical last name (in even years) or reverse-alphabetical (odd years) on an alternating year basis.
