Although little things piss me off like the fact that if you have a guy who isn't playing and you accidently start him then he stays there...I think unless there is an AB then you should be able to change...this is probably with all league though
You know what kills me - Rain Delays.
If the game is delayed before the start you have to let me change my guys. It is hard enough to keep up with all the injuries and roster changes without having to play weatherman.
I also hate that my h2h league played during that shortened all star week. Either combine it with the week before or after or just take the week off. At least make it an option when we set up the league. I sent a suggestion to Yahoo, who knows? (Can you tell I am bitter that I got killed that week!
