A and AA are way separate.. Example, Metro got ran over by Bixby, which Bixby is 2 loses in their season.. SS would get rolled in A ball.. they went 0-9 last year. Kids hit puberty around this age and start getting stronger and a better mind set of playing the game.. cant expect league officials to ask every club before the season even starts if Kids have got bigger, more physical, more aggressive, ect.. Some kids do camps to get better, summer leagues, focus more in practice, fight harder then others for the win.. these are all factors of why teams get better, and its part of ANY sport..
