Huge on our wishlist too. Basically the top of it from a data perspective.
We have new feeds that help us determine games being postponed, but I am not sure exactly how it reflects games that are in a delay. The ideal situation would be, in this case, to not lock players in delayed games and then remove the postponed games from the lineup page. Right now we are only doing the latter, not the former. Kind of the worst of all worlds.
