My francise mode replacing players and my superstar issues

@323446679 Is this happening late in the season?  Are you modulating your weekly training?  Around Week 10-Week12, you pretty much have to switch from full pad training to half pad, you also might want to switch from starters to either split or backups.  Click the lowest right box when you enter weekly training.  You can edit those setting there.  Need to Defense and Offense seperately.
