Problems with franchise mode and tweaked rost

Hi ... I'm italian and this is my first time in this forum.
Well... I give you a question. Probably someone asked that time ago but I didn't find nothing about it. In Franchise mode, tweaked roster sucks. Standings are unrealistic. For example Memphis leads the West ... Kings 13th at West. Is this normal ? Is there a way to resolve these problems with tweaked rosters? Gameplay sounds fantastic with them...but franchise mode no...
Thanks for your help
Ale

i have the same problem as you i made a tweaked roster thats pretty realistinc in terms of franchise teams seeding but i can't edit any players without fucking all the rankings... when i edit one that fucks it all
