There has been a trend for conferences to expand their men's basketball conference schedules from 16 to 18 to 20 to, at least for the Horizon League, 22.

I thought it might be interesting to make a log of how the different leagues are doing it. Some information was easier to find than others, so I just did the best I could. Please feel free to correct and I will update accordingly.

Here goes:

America East: Unclear what 2020-21 plans are after expansion to 10 schools. (2019-20: 16 games for 9 teams. Full double round robin.)
