### A new 9-square featuring former NBA player Ron Mercer

A new 9-square featuring former NBA player Ron Mercer:

Statistically, my estimate is that I need about 76419 words in my 9-letter word list to find a single 9-square. I have 223602, so the expected number is (223602/76419)^9 = 15270 total 9-letter word squares that can be found using this word list. We'll see how close my estimate comes.
