I recently undertook a project in which I read 5-10k game stories covering every game Wilt Chamberlain ever played in. I presented my findings at the Sloan Sports Analytics Conference in March 2026. I am now sharing the spreadsheet that has all of the figures I was able to find. One tab is regular season and one is for playoffs. I found reported totals for 180 regular season games and 77 playoff games. In my presentation at Sloan I also included some additional figures from a source who has access to video I do not, which allowed me to include figures from 4 additional regular season games and 4 additional playoff games. Even without those, I believe this 257 game sample represents the most comprehensive and well-sourced collection of blocked shot figures for Wilt Chamberlain ever compiled. Like the existing 112-game sample, it was easier to find figures from the later stages of his career and so we shouldn’t treat the average of these numbers as what he likely averaged in his career. Nonetheless, the numbers are staggering. 8.2 BPG in reg season and 7.2 in playoffs. My best guess is that he averaged about 8.7 BPG in the regular season and had 9,058 blocks in his career, but that is just an educated guesstimate.

The spreadsheet with links to sources can be found here: https://docs.google.com/spreadsheets/d/111JGC7txe1B_L2GFNp4WLCN0YOOHKu27BqScabeMpKc/edit?gid=0#gid=0

While I read thousands of game stories, there could be some I missed, so please share any with you me that you might come across that are missing. The largest source I can think of that I have not yet mined is the Philadelphia Evening Bulletin. It was Philly’s pre-eminent sports page when Wilt was in town, but it is only available on microfilm at the Philadelphia Free Library and the Temple University Library. I examined a month’s worth of game stories from that paper and did not find any blocked shots totals reported, but there’s obviously a lot more to check. I am just not able to get to the library to spend the time required to read all of those other stories at this point.

You’ll notice that some of the numbers I’ve written are not whole numbers. That is because I’m weighting all sources equally. Sometimes one paper said 8 blocks and one said 9, so I’d write 8.5 The most extreme was a game where one paper said 12 blocks and the other said 1. Usually the difference was maybe 1-2 blocks.

I have added many of these numbers (and dozens of others) to box scores on Basketball Reference.

Hope everyone enjoys this work and please let me know if any questions
