The normal distribution could be used for the frequentie of appearence, but if I understood BB correctly [40492.8 ] and the statement that only 20% has allstar potential or higher still makes me believe that potential is liniaer in terms of star rating/potential. Players with 3, 4 or 5 star potential have allstar potential and up, but only 20% of the players have it (not evenly divided between 3, 4 and 5 stars but something like 15%, 4% and 1%). I am not completly firmiliar with the "normal" distribution, but that would almost mean that only 5 star potential has an allstar potential or up, and so 20% of the draftees should have a 5 star potential...
