Hello i have a naive question,
Is there an optimum value (OV) for height/weight ratio for players ? If not i would suggest a simple formula like this :
OV= (height)^2/weight = 25
At this threshold players would have a nice momentum to carry the ball which would take the role of
acceleration in player's stats.. Above and Below this level one can speculate a gradual decraease in performance.
For instance a player with 1,80 m with 80 kg will have
80/(1,80)^2 = 24,7 player index
Note that this value is leveled by conditioners in professional football teams.
Cheers
