I was wondering if anyone would like to weigh in on this currently pending proposal, though I suppose it couldn't take effect until at least 2019.
In combination with the pitching limit rules already in place, I have to think this would both provide a ton of pitching opportunities to guys who are further down the staff ladder, hasten the promotion of younger guys from JV teams, and possibly result in larger rosters being kept after tryouts end. But I would also think this will lead to a lot of games being much more high scoring, and possibly long.
The idea of having a ton of Saturday doubleheaders seems designed to prevent this from busting travel budgets, but there will be budget impact if only for the additional baseballs and umpires. And I don't know what the policy will be if, e.g., rain comes down after game 1 but before game 2 is official.
I've always thought 20 was too few, but I have to admit that 25 might be enough to suit me.
