Madden has the tools in their system to take into account intangibles and physical abilities as much or more than APFs system. I actually prefer 2k8s system to the current madden one but don't think that is the best way to go. I will agree that there needs to be a clutch rating but the workhorse rating could easily be shown by having more stamina than most other players as it will allow your player to become better in comparison. The problem is the stamina and durability ratings really need to be spread out accross the board making more seperation.
