I wrestled D2. Graduated in early 90s. I had a teammate qualify for the d1 tourney.
Another guy, my roommate was 5th in D2 and had multiple wins over qualifiers including splitting with a R12 guy, including a win by major in their last meeting as seniors.
A lot has changed in 30 years. The D1s are better at recruiting and don't miss on as many guys. The d1 training and coaching is better than it was, I think. Also the lower divisions don't get to challenge themselves as much against the big boys anymore. My roommate had a much closer match against the r12 guy than he thought it would be in their first meeting. That gave him a lot of confidence. When they met each other again less than a month later, my roommate took it to him and even turned the guy. I'm not sure how much that could happen these days.I mean, I was maybe above average d2 and I would hold d1 qualifiers/top 20 types to a regular decision if I had a decent match.
