Why are STARTING LINEUP always changed automatically by CPU?
When I used a roster patch to play a season, I found that the CPU teams' starting lineup had been changed. For example, SA Spurs's center was TD, starting PF is R. Horry, and M. Ginobili was even a bench player. Green Robinson, such a player could be starting.^
Later on I found many power forward had become center, many SG had become SF, and ......^&

Because that's how the game works. There's no option to disable automatic roster reordering these days.

Hey, Andrew, I have probably found the solution to that problem ablove. The 'Secondary Position' also decides one player's real position. When CPU reordered rosters, it will make a starting lineup using overall imformation of a player's primary/secondary position. I did some experiment, such as I edited Tim Duncan's secondary position and made it 'power forward', then he would always be a power forward unless you move him to the 'center' case.

Thanks, but I'm already aware of that. As I said, the game has no option to disable automatic roster re-ordering so it will sometimes make odd adjustments based on secondary positions according to what it believes is a better lineup. Which isn't always the case and certainly not always true to life.
