One wrong decision can ruin everything... just like what happened to Dallas. Last year, they reached the NBA Finals, and now they didn’t even qualify for the playoffs!
Nico is even telling everyone that he did a good decision because they've got AD for trading Luka, well he's got a point when they've been looking for it.
I think management should look beyond just the coach’s performance. They also need to consider the coach’s relationship with the players.
Because what usually happens is, when a team struggles, the GM just points all the blame at the coach.
The management also need to look at their GM. But if someone has got more shares to the team, they're free to do what they want.
That's why Mark Cuban despite that his promise he won't let a generational talent go away but because he's sold the team already, he's no longer a major decision maker for the team.
