Mutant? How does such a player get created?

[TropikThunder]

OK, I have read all the threads about mutant players and tanking and other forms of cheating/manipulation/evil etc but I just have no idea how this player and this team exists.

Player:





This player is maxed out as the note says, with white skills well over 400, and grays well over 300. He's only 19, meaning this is at most his second season, and has only played 37 games. How did he get such high skills in less than 2 seasons? Even if the owner is spending a ton of money, there's no way I can see that even the gray skills get 350+ in 2 seasons. And the owner is not a tanker who just sits in a lower league and lets his team gain while not getting promoted and losing a star (which wouldn't explain this 19 year old anway):








This owner started in December 2016, and has gotten to level 20 in 1.5 years, which means he is getting promoted every season (not tanking).

I don't get it.
