I reckon the system identifies the initial Fast Trainer you acquire as the star player until the end of his career. This makes sense today. When I had Dean Way (a mc, yes a fcuking mc) as my star player and Allessandro Bassi (an amr) was a supporter. Then when Way was sold, Bassi became to the position of my star player, then Steve Knee etc. However, at times when mutants were actually real deal, they were grabbing the star positions. Djorou for instance, was a mutant and he was acquired after Steve Knee, but became the star player. After they nerfed the mutants, Steve Knee became the star again.
Dean Way’s grey skills are not unusual by the way, unlike the Chojaks’, who was a player of my friend Tom.
