We alternate yearly between AL and NL, and to me it is the best way to play. It created a more complex draft and waiver wire situation. To me, it's more scraping the bottom of the free agent pool for the next rookie or young player who may explode. In order to play in one of these leagues, you have to know more then just the top 100 players, you have to know almost all of them. On top of that, we make it even harder by having to start, say 2 RP's or 2 CA. It's not for everyone, but it's certainly more fun for the "expert" fan or fantasy player.
