I'm guessing Catilyn Clark all-time most in USA HISTORY kids 5-16
Today - possibly. Tomorrow someone will make a name for themselves on TikTok and surpass her.
All time though - I’d have to say Babe Ruth. Think about it - a century ago there was no TV and radio broadcast of games were not a regular thing - you actually PLAYED the game all day - not sat around and watched it - and then followed the players via box scores. Ruth was the biggest player at a time where none of the other sports were near as popular. Sure college football and boxing were big draws - but baseball had every kids attention and every male kid played baseball.
As far as CC being an idol today - all I can say is they could certainly pick worse ones. Hell - look at some of the “rock stars” we idolized in the late 80s - is a pure shooting WNBA player all that bad compared to having kids wanting to be the next lead singer of some hair band?
