The rule of thumb for me is I have to stick with the picks I put up at post time.
It will cause a lot of confusion if someone logs in the next day to find out we added or dropped plays.
The only thing I could do in the future is to have a pager service to alert everyone at the same time, but I simply don’t charge enough for my picks for that to be reasonable. Like Chris said it will work against you and for you. Sometimes it’s the other team that loses a player and we get an easy win.
