I was reviewing OSU's D2 schedule. They played a D3 SUNY-Canton in Florida and lost.

My sons old school, a D3, also played SUNY-Canton, 2 days earlier and won.

It is a small sample size so it does not mean anything.
Looking at OSU's D1 Roster, many are D3 transfers. Capitol, John Carroll, and Adrian to name a few. I did not take the time to see how much playing time these players received at their D3.
They did have a player drop down from OSU's Varsity team. I am not sure if he was a walk-on or ever on the roster.
CMU (Carnegie Mellon)has a club team. They have a non student coach. I do not know if he is paid.
