Additional change...instead of the first and worst from 2 different years, we're making it more random. your 2 first place teans and 2 last place teams can come from 4 different teams. Also, there were a couple of instances where two teams tied for the best record (oddly enough, no instances where teams tied for the worst record) In case of a tie, I took the team that had not been a best record team recently. In othe wods if the Yankees and the Giants tied for the best record in 1943 (they didn't..totally hypothetical) but the yankees had the best record in 1942, I chose the Giants to get more variety.
