My 2016 is at Tufts U. Just completed his first semester. I will agree with the above poster, show up in good shape, Not so much the arm(pitchers) but your body needs to be able to handle the fall workouts.
For instance, 2016 kind of felt that coming from a large hugely successful HS program that he would be fine . He learned quickly that every good baseball school has a good workout program. And he was about 75% of what he should have been.
His academics this semester were 4 of 4 all A's ..... I was shocked... he worked his tail off. You cannot go wrong picking the NESCAC route. Contact me when he's 30 and tell me what a great decision this was 
As far as pitchers getting looks after college, not many D3 pitchers get drafted, but it could happen. Throwing mid 90's with command and you can come from any place.
Put the work in, get focused, have a goal.
