Yeah, the whole vibe in the stadium reflects your last sentence and the team is still playing sloppy with no clear system after 9 pre season games.
I wonder if the staff actually have a reason for conducting a practice session other than to put on a show to media. Secondly, do they actually watch game tape or are they just too busy trying to show the league how clever they are cause at this point, the only preparation the staffs seems to be making on game day is on there suits & hair.
