You don't see this with baseball fans, or basketball fans.
I'm trying to finish RammerJammerYellowHammer this weekend, and came across this gem---
"There's one more stop before kickoff---the Bear Bryant namesake reunion at the Bryant Museum. The namesake reunion is exactly what it sounds like---a gathering of people named after Paul William "Bear" Bryant. The museum keeps a registry of such people---they fill out a form headed "I was named for Coach Bryant"and are invited once a year to a pregame barbecue at the museum.
The list is, of course, voluntary and only modestly publicized, so it can't account for everyone named after the Bear---or those who'd been named Paul, Bryant, or Bear for reasons that remain a mystery even to me. But these limitations notwithstanding, the current tally of registered Bear Bryant namesakes stands just shy of six hundred.
