Problem With Season Starting Five

I have a problem with the rosters..if i reorder my own roster or if i load Jimmy roster and i play i single game it's all ok..but..when i start a new season and i going to start a game all the starting five change in some player( the bulls Pf is t.thomas or pj brown,,the heat Pg is payton not williams,the nets center is m. moore ecc..),but if i go in the reorder roster section(in the season)the position ar right...
What can i do??

The new Assistant Head Coach feature has a habit of changing lineups at undesirable times, especially for CPU teams. It's a flaw in the feature that we've asked EA to address in the NBA Live 08 Wishlist.

there isn't any solution to fix it?(it's possible change it with db commander or oder dbf editor..if yes how?)
i can change the starting five to the team that play against me each time,but not exsist a solution for the simulation..for expl boston start every game with olowokandi ecc...it's impossible to play a realistic season with this game??

No fix as far as I'm aware, sorry.
