it is not about replacing kenny, it is about picking up otto and dropping kenny, amanek and jackz. They can then rebuild around the ex-Cr4zy core, that has a major slot.
If Kenny wants to play on more international roster, he can try, but I think they should at least drop jackz, amanek and maybe malek. Imo otto is the best player of the cr4zy major roster to pick up. I mean, do you wanna get either espiranto or letn1 ?
