I thought of twenty changes that have come to the game since I started watching in 1971, including two changes that have since been rescinded and the one that is being proposed here. I ranked them from best to worst. I'm not including changes to free agency, drafts, compensation, arbitration, trade deadlines, waiver rules, qualifying offers, injured list, etc. I limited it to things that more directly affect what happens during the game and how the postseason field is determined. The first section are things that I feel mostly positive about. The middle section is where I'm more or less neutral. And the bottom section are things that I feel mostly (or entirely) negative out. Please feel free to chime in with your own rankings!
