Wouldn't recommend trial and error. They need to know they will have very different time frames and demands from the rest of the students. When others are socializing until 2am they need to know they have to be up probably by 5:30 to lift. Make sure they understand the importance of showing up in shape and that they have to budget time. Stay on top of classes from day one. Make sure classes, eating, baseball and rest are priorities. They will have a social outlet with the team. Stay away from Greeks the first semester if not longer. By 4-5 weeks they will be exhausted, worried about school, baseball and probably everything. Be a good listener. Hardest issue however is the player who gets behind academically and is trying to scramble to stay elegible while trying to play BB at a level they have never experienced before.
