The thing with sports games is that the sport doesn't change on a yearly basis, so how do you change the game based on the sport? What do you add? Fifa already includes almost everything you can do with football, so what do they add to each game each year? The only thing they can do it refine the controls and game mechanics, and the overall feeling from reviews and players are that these changes makes the game feel new. That's a good thing.
Also, as a novice player of the game, I'm pretty sure that we I will be able to notice the changes, but any experienced players will immediately notice the changes.
