I'd say their players are pretty stoked about being in a superbowl. A lot more is being made of it than necessary in my opinion. These things happen in sports, it's part of the game, all sports have a litany of injustices through their history. It doesn't justify anything of course, but this is life. These days people are a lot less resilient when it comes to this sort of thing so I'm sure the uproar will continue for a while yet.
I used to bemoan every penalty call etc going against Arsenal in this way, but eventually you just tie yourself in knots with that, it doesn't get you anywhere. Matches are decided on small margins and those margins are eventually forgotten.
