I highly doubt he would tell the press anything as far as that part went. I have two thoughts:
1. Rex may have done this as a "test." After the game some guys said they'd be in on their two days off to go over film and find out what went wrong. Maybe he wants to see who cares and who doesn't.
2. I guess we will see Monday night if any changes were made. My gut feeling is we don't see anything and it's another embarassment.
