In that case why release them at all? Tuesday is good because it keeps RL in the press for the whole week. Wed Arvo is already fine due to Thursday night footy etc. Tues allows for:
Monday Weekend wrap preview of MNF..
Tuesday MNF review
Wed teamlists
Thurs preview of TNF
Friday TNF wrap and preview of the rest
So if we are going to release teamlists Tuesday is the best day
Team news on a Wednesday in the papers is normally only a small portion of NRL news that day so I don't think it is that much of a big deal not having that day. There will always be plenty of other stories about.
If the NRL forced clubs to do a decent amount of media work and have all players avaulable for interviews every week we could actually see a lot more content mid-week. But that's a completely different argument
