If we’re just wanting to mix things up, how about scrapping the “tiers” of players and changing it so everyone has to have a complete “team” of fielders? Three outfielders plus the five infielders and a DH. Then, when you make a transaction, it has to be for the same position. If Anthony Rizzo gets hurt, you can only replace him with another first baseman. The DH slot could have any position (like a flex position in fantasy football).
