The reason people object to it in Madden because Madden has very high-percentage plays due to inadequate and faulty AI as well as gameplay mechanics. That's not the case with real life football. In real life football, if you keep doing the same thing over and over, individual players will adapt. They will jump routes, shade receivers differently, play the gaps differently. This just isn't the case in Madden. We are very limited in our control of our players. Sure, we can control one player but the other 10 are still dumb.
In Madden, if someone knows your exact playart, it can still be a very successful play if you are good enough to make your read. That's not gonna happen often in the NFL unless the other team is the Rams or something.
