Guys, I just put this up as a base from which you can start modding and adding new content, I don't really have much time to add other things, but more importantly I really don't have any skill at doing that!
Anyway, I think the rebounds problem can be solved only fastening the game tempos, but that way you get too much ppg...so I just settled in having about 3 rebounds less than in real, but REALLY GOOD ppg stats. Shooting % and everything else are just as good as they get. I really put my brain into it but, unless I get how the scripts behind this game work, I can't do a better job than I already have.
In this last update, I also edited playingtime/sobstitutions for each team, and also included the sliders and options I'm playing with. Sliders are made by theenemy, a xbox360 user.
Here's the link to my uploaded roster, probably final one I'll be putting out:

Sorry if someone was expecting me to add players or anything else, but this is a roster for the real modders to work with...they won't have to edit all the ratings and so on, if any of them wants to use it, fine. Other than that, this roster is just made for association/dinasty lovers like me to make the game less frustrating/more enjoyable.
