I know a lot of members here on this site are not American, and don't know much about AMERICAN FOOTBALL "the real football" so i kinda forgive you for not knowing.
And a lot of people have been jumping into the chat box saying, "oh did you see Nolan point out Robin in the football scene?" "Nolan is so smart putting in hints of Robin in the movie"
Well, I'm sorry to say you're wrong! "not really sorry"
We all know that the football scenes were filmed in Pittsburgh at the Steelers stadium. Well, there just so happens to be a wide receiver by the name of Hines Ward on that team (he was just in dancing with the stars awhile back if you saw that), and THAT is who they used in the movie. Sorry to pop your Robin bubbles.
