My son chose the D2. The argument you gave in your original post was the exact argument his D2 coaches gave to convince him to go there. Chances are much better to go to the World Series with the D2 team. From watching D1 & D2, the biggest difference I see is the depth of the pitching in D1. Top D2 teams can field and they can definitely hit. Most have a very good starting rotation, but things drop after that. So you wind up having higher scoring games. I might not be totally accurate, but it is my observation.
Renegades5, if you don't mind my asking, where did your son commit to? We may windup running into each other.
