SpeedDemon’s post is a great starting point. Figure out which school he fits into academically, then try to determine which fit athletically. Every year there are 20 or so good players who are academically qualified for the top 4 or 5 academic schools. Once those kids commit (usually August-September), the coaches begin to fill in the rest of their classes. You can outsource a lot of this to PTW. They can tell you pretty quickly which schools will be interested and how many kids that coach is looking for. They are also very honest and don’t beat around the bush.
Does he have a wicked changeup or curveball? Throw a funky pitch that gets outs? Every team has a spot for a reliever specialist.
