well first off.. lebron is a 25% 3p shooter this season... second, i have retuned the 3p shooter higher in the game engine i am using to simulate nba games.
I think retuning the 3p shooting is something we should consider doing for the regular GE as well... this is part of what we hope to learn by doing this nba simulation... for with real nba players we know what the results should be...
I would also add that yes, I think that in general buzzerbeater defensive ratings are higher than the nba defensive ratings i have chosen.... though that choice was arbitrary.. the combined tuning/ratings is what gives the overall percentage.
