Boy 2020, I am not sure your comments on Wisconsin are accurate. For years, that conference has been one of the strongest in all of D3 baseball-yes, I know, the one where anyone could play. If you think that, you must know D3 at the bottom, not the top.
This guy was a 2nd round pick out of Stevens Point:

The State of Wisconsin produces many high quality college players. They just don't leave the State and play D1, but many certainly could. I would strongly support broadening horizons on college baseball. To provide a current illustration, one of the top 10-15 Summer Wood Bat League teams in being led in many offensive categories and games played by a high quality D3 outfielder. Every other player on that team is from a D1 program most would consider top 25-50. Why not grab your son at the end of next May and head to Appleton, Wisc and watch some D3 college CWS baseball. It might be good for both of you.
