I echo all the great things that have been said about OPL.
One suggestion for 2022 would be to increase the number of SP slots from 2. My co-owner and I ran into a scenario where, going into the year, we rostered ~7 IRL aces. Even over the course of the full half, they never quite unbunched (we still had as many as 4 going on the same calendar day heading into the break) and I’m confident it made the difference between making and missing the round of 32.
The 2 slot rule seems to mirror capless H2H formats. It is my understanding, in normal play, this rule prevents a large volume of low-quality SP adds prior to the matchup. With the long-term scoring periods, I don’t think this concern really applies in OPL because you will be effectively stuck with the low-quality pitchers for the entire duration of the period. In effect, the 2 slots work against a higher-than-average number of high-quality pitchers. This type of roster construction seems to be a legitimate competitive advantage. In other words, I don’t see any theoretical reason to advantage teams built around hitting over teams built around pitching.
Thank you for your consideration and keep up the great work!
