The Hall of Fame Index was first published in 201o. It had been in the works for nearly a decade at that point. The whole point was to establish a systematic way of looking at Hall of Fame candidates and those already in the Hall of Fame. At its best, it measures fitness for the Hall of Fame and aims to put players into groups with other similar players so we can compare them.
The sequel was published in 2020. It obviously updated numbers for players that were currently active, but also adjusted the formula as we got more information. One of the key things in statistical **** ysis is that we are always learning something new. The formula is similar to JAWS, but has a couple of key differences. First, it combines baseball-reference.com WAR and Fangraphs.com WAR into one number. I do that for two main reasons. First and foremost, the more data the better in most instances. It gives us a cross-section of what keen sabermetric minds feel about a player.
The second reason is that there is always an intellectual divide on these things. The old formulas included win shares, but since Bill James retired, there is no longer an update on current win shares, so that one has been dropped from the formula. Like JAWS, the index includes a peak value element. However, the peak value is made up of ten seasons. I have gotten push back on this and the push back is perfectly reasonable. I chose ten years because you need to play at least ten years to get into the Hall of Fame and ten years gives you slightly more data than the seven years that JAWS brings.
That is important distinction because I do not profile any players until they have been in the league for at least ten seasons. So, as we compare Alex Bregman to his contemporaries, there are five third baseman that make the list. I will not speak for Jay Jaffe (the creator of JAWS) but the index was never meant to rank order players. It was meant to place players into groups with other similar players so that we can directly compare them using other means. I have done this before with Bregman, but since we are at the midway point of the 2026 season, it is a good time to revisit it.
