If the front office believes that the team can compete for and win championships with Curry on the roster, then, there is no way that the team trades Curry.
If it is determined that Curry cannot lead the team to compete for more championships, then, now is the time to trade him to a team which can send back both players and and a haul of draft picks. New Orleans would be an ideal trade partner where the Warriors could send to the Pelicans Curry and the Warriors could get back Lonzo Ball, Brandon Ingram and a haul of draft picks.
As of now, there is no way that a "returning from two season-ending injuries" Klay Thompson, a "no-defense-playing and diminutive" Curry, and a "declining-offensively" Green, with Wiggins, Poole, Wiseman and Co are competing for a championship.
While we are all pleasantly surprised by the emergence of Wiggins, especially on defense; Kevin Durant masked a lot of the Warrior roster deficiencies, which Wiggins cannot. Much of the blame for Durant leaving falls directly upon the shoulders of Kerr and his inflexible coaching style.
If the front office decides that the best path moving forward is to run it back again with "Curry-Thompson-Green," then Wiseman has to accelerate his growth curve and the team has to hit on one of its two first round draft picks with a player who can step in and play immediately.
Lastly, why are we asking if "...Curry really wanted out right now," instead of "can this team still compete for championships with Curry on the roster," and, if not "what can the team get back in return for a trade of Curry?" I would rather see Myers and the front office take an aggressive posture moving forward instead of acting defensively and waiting for what Curry decides to do. Myers and his team should have done the calculus before Durant opted out and moved him, Durant, instead of having to scramble after Durant had signed with Brooklyn.
