I don't know if I want to generalize, but here's my experience. My son played ball in Jacksonville, Fla., from third grade till junior year in high school. I always thought the mild climate was a real advantage, knew that a lot of good teams and players come from the Sunshine State and frankly expected a dropoff in talent when we moved to middle Tennessee last summer.
The first surprise was when tryouts for school ball were held in the summer. In JAX, conditioning was voluntary and didn't start until Thanksgiving, and the kids didn't even know if they were on the team till February.
His last-period class all year has been strength training with other baseball players. In Florida we had some sort of sophisticated block class scheduling that made that not even an option.
I was surprised by pretty much every school I visited having an indoor hitting facility, and with the long list in the newspaper of coaches and former players offering individual instruction at a price. In Florida, all I was aware of were camps at colleges during the Christmas break and summer.
All in all, I'd say the year-round focus on baseball is greater here, though as I suggested at first I have to admit it might be more a comparison of one specific program to another rather than between states in general. Perhaps I'll have a better idea about the quality of talent in a couple of weeks when the games begin.
By the way, I enjoy the site. Thanks for doing it. Sorry for the long post.
