i just spend the afternoon on finding out why scoring especialy(and all other averages too) is way too low(League Leaders never crack 30ppg) in Season and Assossiation Modes.
Here is what i found:
Problem 1: Minutes
no matter what you set at your Roster Rotation if you play with Injuries on it will get messed up:even the Star Players(Durant,Bron,Dwight,Melo) almost never go over 35 minutes per Game.
Realistic would be around 37-40 minutes for Star Players
Problem 2: Way to few Free Throws
even with the "Draw Fouls" Tendency up to 99 Lebron and Durant averaged only about 4,5-5,0 Free Throw attemps(yep not even makes: attemps!)
Realistic would be 7-9
Problem 3: Too few Assists per Game
even the Leaders rarly crack the 9.5 Apg mark. Chris Paul and Rondo usually get to 7.5-9
Realistic would be 10-12
sadly i still have not found a way to correct this.
sure if you are in Control of a Team you can assign 40+ minutes to a Player but it doesn´t help with the other Teams.
and i also spend time changing the coaching Profiles with little effect
i know it isn´t a major Issue for most but for a Sim Fan like myself it really can dimmish the Mode..
when your Leaders never get close to Real life Stats on every other Team besides yours.
i don´t know if there are any changes we can make.
i would love to hear your ideas to this

oh and apologies for my English.. i am from Germany
