First, the obvious: Zeller is 7 feet tall. Sure, that’s not so uncommon in professional basketball, but just for fun, consider the fact that being a 7-foot tall human is so rare that the Center for Disease Control doesn’t even keep track of statistics for them. Zeller also has two brothers who are just as tall as him, a factoid which most fans are at least peripherally aware of, due to its near-constant use as anecdotal filler for broadcast producers and commentators around the country.
(Quick tangent: If you’d like to do some fuzzy math, per an old SI article, you can reasonably determine, that of men between the ages of 20 - 40, fewer than 70 of them are 7 feet tall.
