What does "better contact physics" mean? More accurate? More varied responses? The fact that basketball has to deal with a tighter view means it can get away with collisions that's don't line up like they do in FIFA. And as precise as the movement needs to be in basketball, you can't get away with the limited steering you get in the FIFA jostling cases. Then there is the vertical plane that basketball has to deal with SIGNIFICANTLY more than soccer.
You make a good and fair case for your point, so I won't beat this to the ground. I just want to reiterate that the differences in the dynamics of the sport and video game lends FIFA quite a few advantages. But if you don't agree, that's fine.
