In regards to the first two points, I can answer both because I was at the film shoot for the football game in Pittsburgh-
1. No, the Rogues are not the away team- The game is the Gotham City Rogues versus the Rapid City Monuments. I'm honestly not versed enough in comic lore to know if either of those are a reference to anything, but take that as you will.
2. This is the second time I've seen mention of the "R" looking like a Robin sign. I don't think that means anything- We were encouraged to make our own signs, and as far as I know, that was just a Bat-fan showing a bit of hidden love with his own sign. Now, why Chris Nolan decided to focus directly on that particular sign in the trailer is anyone's guess.
