Go to top of section 131ish at end of game and be ready to bolt out of gate 2 exit at the final whistle. Turn right out of the exit and secure a spot on the barricade. Guard spot with sharp elbows. Make yourself big to secure more real estate. Wait 60-150 minutes for players to exit. Shout their names. Don't call them by the wrong name (as I did with TMac/Grabavoy last year). Have a sharpie and something to sign. If possible be a hot 20 year old woman or a cute 10 year old child.
Follow these instructions and most of the players will come over and sign. No guarantees though.
EDIT: clarified section number.
