To play college athletics requires a tremendous amount of time and resources. Not only athletic skill is assessed by colleges but grades, character, amount of time in weight room and the kind of teammate a player works to become is looked at by colleges.
Scholarships are very difficult to achieve. Athletes and parents need to be aware that most players will not get a scholarship but the showcases are used as a tool to become a walk on as well. This is a great way to get a foot in the door of a collegiate program. This will be the path of most high school players. There are TONS of colleges out there that will give opportunities to athletes that WANT to play.
If a player wants to play college baseball, it starts in the classroom and weight room.
