I suggest your son attend one of The Complete Showcase events. There are a number of them in DFW every year - usually in McKinney. The events don't cost very much and are well attended by college coaches - mostly D2, D3 & JUCO. Every player gets a written evaluation (usually from 4 different coaches) and a chance to discuss the evaluation with the coach(es) that wrote it. This is a good way to get a feel for where your son fits after high school. Once you know what your target is you can then develop a better strategy.
