That is interesting and I am sure there is a good point there but meteorologist is also a profession requiring a high education level. Yet the meteorologist list (Bill, Joe, Jim, Jeff, Mike, Scott) is way more similar to the football coach list to the point where 3 of the names are the same.

Perhaps it's because individuals in public-facing professions/roles tend to favor shortened versions of their names? I think this is largely why the media makes fun of Benedict [Timothy Carlton] Cumberbatch.

Stage names. No newsreader on a newscast is going to say "Thanks for that great lasagna recipe, now lets talk to Ebenezer Ulysses about tomorrow's rain", they're going to get a stage name of "Bennie" in that case.
