Midge, the guy that came up with the mad ast% teams was the one that came up with that. He called it "Six Minutes of Hell" and made sure all of his players were guys that barely shot any 3s and made them all (like ending a season 1/1). The way 3-pt offense used to work, it didn't recognize that a player wasn't likely to shoot many threes, it just took the highest perimeter/usg combo guy out there & he let loose... and since these guys hit 100% irl, they hit close to that in the sim. It was pretty genius, actually, but so ridiculously unrealistic...
...kind of like the State Farm concept.
