Dolphins Stadium Help

I am travelling from Mexico to Miami to see the Dolphins-Seahawks game, and while it is not my first game it is my first one since I was about 10 or 11 years old. My seats are in the 100s and I have sideline passes, but my question is where do some of the extra events take place? For example some players give autographs as they leave the building after a game and I do not know where that is. Does anyone know, and can anyone help?

THANKS! :D
