From my experience, it is nearly impossible to replicate the real NFL season in Madden. With that being said, with the new sets being produced after the most recent patch, there are some pretty nice sets available on the forums. I recommend going through a few in a test franchise and seeing what results are best fit for what you're looking for. I'm currently rocking with Armor and Sword's AM set and I'm getting good animations, pretty realistic stats, and most importantly of all a good, clean challenge. Check his out but like I said, go ahead and test other AM sets as well to see what you like best
