You are comparing players in their teens on junior contracts to a key member on their team with a long-term grown-up contract, that's the real BS. Those situations are not comparable. Furthermore, it's the last year he is only eligible to sign ELC which would most likely actively lose him money. Established EU pros don't terminate their contracts to go to "training camp in the summer".
You questioned yourself why there is "no conversation" about him, I tried to explain it. If you have better theories I'm all ears.
