AcademicsFirst- Good thought process. I apologize if I came off as blunt, I've just seen a lot of people in your position going way overboard in relation to the process.
I've seen 96 mph fastballs in D3 baseball and 75 mph fastballs in D1 baseball. The only thing you can do as a player is work as hard as you can to be the best you can possibly be, both in the classroom and on the field. Once the time comes, getting a gauge of where you stand is easier than some think. If you get yourself into the right environment, the individuals observing will be forthright with their evaluations.
Best of luck, keep us updated.
