My daughter who is going to be 12 was on an all 11 year old team last season. Established organization, new coaches and an extrememly talented bunch of girls. By the time the season was over, the experience was so bad I'm certain that at least 7 of the 12 girls didn't even come to tryouts, and it may have been as many as 10 of 12. I wonder how much of the movement is from committing to a team, things not going the way you were told, and people moving on. My family was intending for this team to hopefully be her last move...and it didn't work out. Definately wasn't a good situation.
With that being said, I have attended quite a few tryouts this year, and noticed a couple things. It seemed like there were not a ton of 12 year olds at these tryouts, and the talent level seemed a bit average overall but there were a few studs...maybe I was hoping for all STUDS!! The 13 - 16 year olds seemed like the numbers were huge, and there was some serious talent there...serious STUDS! 17 and 18's seemed a bit scarce, but I've never noticed a ton of them at tryouts anyway. There were more 10's then I remember in the past, some really good ones too. I actually saw an 8 year old lefty slapper! She was running and slapping...it was unbelievable! I told my 12 year old, I would've taken her on my 10U team 2 years ago. She was amazing!
