Wanted to mention Hillsborough CC in Tampa, FL. Coach Gary Calhoun is an excellent coach with credentials and he has a fine staff. Coach Mike Sodders is their pitching coach with some excellent pro experience. Hillsborough plays their home games at Legends Field (NY Yankees) which is connected to the Hillsborough campus. What a place to play and practice...
I agree with the other posters, all good programs with sound coaching. While there will always be someone not happy with their individual experience, you have to take that for what its worth, an experience. IMO, the FL JUCO's are all competitive and their goal is to get their players to 4 year schools and the professional ranks if applicable.
Bottom line, check them all out and see what is the "best fit" for your son. In addition to baseball, check out the academics, courses etc.
Have a great day!
