MyPlayer roster update?

[RayZLAL]

Got traded to Clippers and I see that Blake Griffen doesn't get much time and his rating is down compared to latest roster. I start myplayer with the Opening Night First ever roster update and I was wondering if there was any way to edit the MyPlayer file to update the roster for the players or rotation times (I never get to play with Blake since his rotation time is bench mins).

thx in advance
