You can do this with 2 controllers. Go to Play Now, now once your in there selecting your teams you can go into another page, where you can create another Madden profile.
As long as you play with seperate Madden profiles for each controller you can unlock achievements....that being said.
Pick 2 teams, really don't matter, I use Patriots against Browns. Now, when you select the defense play for the Browns go into By Playtype>Special Teams>Field Goal Block. For Patriots offense By Playtype>Shotgun Pass>then pick any play in here. You will want to get your pass of quickly after the hike, pick a button, every reciever should be wide open. When Browns get on offense, just have them punt the ball to you.
