A suggestion (since this is the Suggestion forum). Why not give the NT-coaches an additional option to shortlist some players? If sacked from a team, players on the NT shortlist would be released to the TL as free agents, rather than end their careers. A feature like this would have no impact on NT game shape like releasing/adding players would have.
I believe this would be fair to the NT-coaches (including helpers) that from my experience devote a lot of time mapping out and keeping track of talent, giving advice to owners, and so on. Might seem trivial to some, but it's unbelievably shitty to see prospects perish like this. If I wanted to keep those really into the game (people around the NT) motivated, I'd do something about this..
