Now I know Cam and Caylin are pretty far apart in age but.........
I'm always amazed when two guys can have the same parents, grow up in the same house, eat the same food but differ so much physically.
MJ was the same way. His dad and brothers were like 5'11" or so but MJ had this magic growth spurt and ends up at 6'6". Caylin is like 5'11" 200 lbs while big bro is 6'5" 250 lbs. Obviously talent, hard work etc., matter a lot but in football you need God + luck + genetics + talent tbh.
Height wise they were different but MJ brother was the original 'Air' jordan, Larry was 5'8 doing windmill dunks and shyt that genetic athleticism
