You told me nothing I didn’t already know. Where I live there are NAIA schools that play baseball. Only one level. They regularly play the D2 NCAA schools to help fill their schedules. They are technically not d2 but everyone here calls them d2 because that’s the level they’re competitive at. Similarly there are club baseball teams in the area. They play games against the NAIA schools as well the d2 NCAA schools. They don’t fair that well and are considered slightly below D2 baseball but probably D3 caliber. It’s much easier just to use the d2 or d3 level to categorize them. I probably should have called FGCU hockey a d3 school since that’s the level they’re closest to but as you already stated there isn’t d2 or d3 in hockey anymore. I used an easy term to describe their level of competition.
