I really like the concept. I considered doing something similar with Shaq & Kobe but ultimately decided against it with how much roster editing would be needed for it in 2K19. It's a very cool concept though and I look forward to seeing where Kobe goes in Phili.
Just curious as I can't remember, in 2K14, can you change the Peak Ages for players? Or do you need the roster editors for that sort of edit?
