Yes. All of it. I think we could make bigger strides developing this game if we could compare player weights, game plans, rules, play selections. All of it.
For example I'd love to see the min max game plans the last super bowl winners had to see if there is any strategic way to counter it in game, or if they've just found the magic % that is already going to give best results.
I think it would also be interesting to see player weights and use those to adjust league weights or provide tailored player weights for certian game styles at least.
Mfn 1 should be about testing, breaking, and making the game better... not who can min max the perfect team in secret right?
