He's still only 11 (12 in Nov) but went from the small field to the big field in August playing in 14u. Best decision I ever made.
You act like there is a choice. If team X decided they needed whatever the 11 year old had to offer (likely speed), then team Y has no control over that. I would suspect that the 11 year old would not be able to truly hang with the elite players in that age group. That is where levels come in. In GA there are Major/AAA/AA/A teams. The AA teams do not play Major teams and the AAA teams don't play A teams. If you have a high caliber player there is an appropriate spot for them. Conversely, if you have that 14u kid that is still 5' tall and 95#'s there is a level for him as well.
P.S. I'm positive the poster meant to say 30" not 30'. I've seen PG score of 10 catchers throw a bouncing throwdown 30 inches out so it's not unheard of.
