I don't know if it's been done before, but the idea is to make a P4P (current) and an ATG list based on which fighters were good for boxing, did good things for the game etc... For example, PBF was making it to the top of most P4P lists but didn't take the biggest fights out there, so he wouldn't be highly rated on this kind of a list. It would also be good if you could explain why the fighters you chose make your list.
