We've talked about the subject of verbal commits before and the ethics of giving your word and then not following through. The expectation is that a verbal commitment between a baseball player and a college coach will be honored by both sides. So, IMO, the statement "it doesn't really mean anything" is very wrong. Yes, you have not yet signed a contract. However, giving a verbal commitment means you & the school are agreeing to a scholarship offer and that you will attend that college in the fall (if all academic admission requirements are met). Breaking a verbal commitment might happen more often in other sports, but in baseball it is not the norm. So, as a player if you are not sure about an offer, DO NOT GIVE A VERBAL COMMITMENT. You are risking your good reputation.
