Not a stupid question. Sim just means that you play the game the right way. Some people use the same play over and over again. They try and do things that take advantage of the AI. Things that you wont see on Sunday. Like dropping the QB back 20 yards on a pass. Sim is just playing like you see on Sundays. Real football. You don't have to play the right way to use these I just wanted everyone to know how I designed them. So if someone cheese's a lot and they won't complain about these being to easy.
