Bird was listed 6'9" barefoot, Magic is closer to 6'7" barefoot and Jordan is around 6'5" barefoot (think it was 6'4.5" if you want to get technical). In pictures next to Robert Parish (legit 7'0" barefoot) and Kevin McHale (I'm guessing 6'10"-6'11" barefoot), Bird is a little shorter than them. But shyt, looking at that picture of him next to PG (who's probably 6'9" barefoot himself), Larry would be closer to 6'10" barefoot. Pretty much all measurements before the 1970s were taken without shoes but between the '70s and early '80s it's hit-and-miss.
Larry was also just a scrappy motherfukker, he was tall for a small forward but hovered around 210-220 lbs in his prime (even said he was as light as 206 in the summer of '86 in his book Drive) and wasn't explosive. Man hustled until he physically couldn't anymore.
