Fantasy baseball is always changing. Sites try to be different by adding new services, features, and league formats. For the hardcore, the most esoteric information is often not only desired, it is considered essential. We have weekly transaction leagues, points leagues, roto leagues, daily transaction leagues, draft-only leagues, etc.
So, what will the "next-generation" of fantasy baseball be like? I have a feeling that at some point, we're going to not daily transactions, but in-game roster moves. Want to bench a player halfway through the game? Sure ... but he stays on the bench. Want to pull the pitcher yourself when you think Dusty Baker has left him in too long? Go for it.
Imagine the possibilities. You think people in daily leagues are too obsessive, just wait until they can manage in-game. Someone's going to do it. You mark my words. And the first time I get to pull C.J. Wilson when he enters the game in a non-save situation or Oliver Perez when he's walked his third batter of the first inning, there will be no going back.
