Do your homework... seems like a popular theme...
Can't agree more. See if you can contact parents of former players... Some coaches are different in front of parents as opposed to just in front of the team.
Don't count on anything until a written offer is given to you. And ask for one (at least an email), if a verbal is offered. It was amazing how an email was able to clarify things at a later date...
My son was told many things that never materialized. What an assistant coaches says doesn't count much unless you hear same from the head coach.
Find a school that "fits"... IE environment, academics, coaches, Scholly amount, remaining costs, conference, playing time, weather, facilities, dorms, whatever else you might be interested in...
Remember, "FULL Ride" is almost non-existant in baseball.... And things can change from year to year, but baseball now has a sit a year rule to transfer.
Some schools want you to wait a while before they offer... (ie they have others ahead of you) others want you to committ immediately... (IE they want you but have others they could sign) Talk with the coach, be honest, ask questions. Don't rush.
