Currently, my D-II team in Crum is 62-5 all-time vs. a team that has been sim for all but about 8 of 41 seasons, though they haven't been sim much in the last 6 or so years. I know we haven't lost to this team in 15 or more seasons. Plus, I know the vs. records don't go back to the beginning.
What are some other records out there?
(I realize I've jinxed my team for tonight's CT semi, but the other team isn't a bad team anymore. Currently 5-0 vs. the new coach, but they've been steadily improving.)
