UCSD played (briefly) with the CCAA in the 2020 season. I'm not sure if they are/were supposed to play with Big West in 2021 or if that comes next year. We have a user here who would know.
Chico State has has a lot of success and WS appearances and probably belongs on this list.
Oh, and there is another program in transition here. Dixie State is moving to the D1 WAC
Thanks. I was not aware of Dixie State moving.
Chico State didn't make the top 30 rankings in 2015, 2016, 2018 or 2019. That knocked them off my list here - although they were very good in 2017 and looked promising when 2020 started.
