I've been thinking about Andrew and Aaron Minyard lately and how their height is depicted in fanart. So I was looking into the shortest athletes in American history and found Jack "Soapy" Shapiro. The shortest player in NFL history coming in at 5' and half an inch, also weighing 119lbs (the only American athlete I could find under 5'3")
Born in 1907 Jack Emanuel Shapiro was the seventh child of Jewish Russian immigrants, and was raised in the Bronx. He played for the New York University football team in 1927. Unfortunately, Jack only played one game in the NFL for the Staten Island Stapletons in 1929 against the Minneapolis Red Jackets. But he technically went pro!
So Jack is center at 5'1/2", meaning the man on his left is probably over 6' (so like Kevin/Matt sized?) and the man on his right is about 5'6" ish (so Nicky size?)
I don't know if this is helpful to anyone, but I fell down a rabbit hole and wanted to share my findings.
