Seriously, this would be useful information. I think the other banners are hanging towards the Girod Street Endzone (Gate E). I'm not exactly sure, though...
Actually they are opposite of the Girod Street Endzone hanging over the Poydras Street Endzone. That's Gate A. I know this because my seats are on the wall in section 103 and I have to turn around and look up to see them. The banners for the honored players/contributors are on the opposite corner of the championship banners in the same endzone.
