I've always referred to the Ivy and Patriot League as "hybrid-D1s" . Their competitive level is D1 but their reduced game schedule , reduced travel and reduced practice time are very D3-like. All of this is a major reason my son pursued this direction. As an engineering major it was not going to be in the cards (for him) at any other D1 than an Ivy or Patriot school. If there was a D3 engineering school that he had ranked higher and offered, there is no doubt he would have gone there.
As always, JMO.
I agree with your point, but to clarify most or all Patriot League teams play a full D1 game and practice schedule. And like Ivy's, they have a 4-year-and-done policy (i.e., no redshirting).
