I'll be honest. Until you brought that up, I had forgotten that Scranton even had existed. I'm not really that good at the history of D-III hockey, and doing this research helped me learn about some of that, including how strong some teams were in the past.
I've been following D-III hockey for about the last seven years; but only recently have I been following the whole landscape of D-III hockey, and not just Fitchburg State and the ECAC. I don't have a good grasp on teams that existed ten years ago, and don't today.
The first three lists are meant to consist of the 72 D-III teams that currently are active, plus any team that happened to receive votes or be ranked during the timeframe of my research. RIT happened to be the only team that doesn't play D-III hockey anymore and received votes over this stretch, which is why they appear in these lists. As for schools such as Scranton and MCLA, I never came across them in my two dives through the poll archives (and sort of forgot that they ever existed). Therefore, I didn't include them in my lists.
If you guys want me to include folded programs in the lists, I'll do that. Just give me everyone I missed. Of course; If I include them, those programs would only appear on the "never received votes" list, since that's the only list they qualify for.
Sorry for any inconvenience.
