I think it will actually fit H2H perfectly. We actually divide the season into 5 different 5 week seasons. We have two divisions (upper-Hobbs & lower-Ueker). Top three from Ueker move up to Hobbs and bottom three from Hobbs move down. This happens for four "seasons". Then we seed each team based on total time in the Hobbs division and have a playoffs for the last 5 weeks. It works perfectly.Huh. I wonder if this makes fantasy baseball viable. I'm in a H2H league, so probably not enough games for that to work, but maybe an all-play type of thing will work.
For a shortened season like you said we have talked of just having a single "season".
