We know they have numbers because every game engine requires data to be used to perform its actions. It could have been as simple as a player having a 1-4 in a given rating. At level 1 they had basic abilities. At level 2 they perform regular actions. At level 3 they perform advanced actions. And finally at level 4 they are experts and make those eye popping actions.
The difference between madden and 2k8 is madden instead of saying 1-4 they have 40-99. Everyone issue is that madden doesnt have enough animations to properly represent the elite from the scrubs and people have formed an erroneous belief that 2k8 was more complex/better because of the game play. From the franchise perspective,(considering players are rating 1-4 with 2k8 and madden has 40-99) 2k8 is on an elementary level and madden is in high school.
You say that the game needs to simplify its ratings and move to a 2k8 set but how would you have progression work?
Here is an idea of what madden could do with adding in a "weapons system"/adding more ratings for more abilities.

If more animations were added in that way then the game would become extremely more complex and realistic.
Your issue with some of the ratings being redundant is fair. I have another idea of how to make some of the ratings matter more and make the game more realistic. This would allow for strong players who dont know how to properly use their strength perform accordingly.

Specifically speaking, footwork and agility arent the same thing. Agility is a physical skill set and footwork is a technical skill. Someone could not be able to change directions well but could have trained to bend properly and move skillfully. It is slightly different with agility and elusiveness. Agility is a physical skill set and elusiveness is the manner in which someone can break a tackle without using a move(in practice elusiveness is more used for the truck stick with players who cant truck) Players who have great juke/spin moves but arent elusive tend to get tackled much faster then someone who is elusive but has average moves(RL speaking not madden because of how madden uses elusiveness)
