Well Carmelo is still hoping that one team will get him for this season, there were even rumors that some Chinese team are interested on him. We have seen Dwight move to that country to pursue his love of the game.
But I guess Carmelo has that pride in himself, and maybe believed that a team will acquire him for help. However, we all know that every team has settled down already and for me there are no teams right now that will be a perfect fit for him. Same here, no hate for him, but I guess it's time to really retire and he is no longer in his prime unlike Lebron.
He expressed that he will not play overseas and will wait for the chance to play again in NBA. But after this season, if no one gets his service, I think that will change. Dwight Howard is quite successful in Taiwan and paid handsomely. If he still wants to play basketball, overseas is a good idea. Even at his age, he will still be very competitive in Taiwan or Korea.
I go for Cousin too, he can still play game and can give some minutes for Ayton while resting, Cousin can provide both offense and defense
No hate for Melo but if in case that Suns will sign a veteran.
But with your first statement, who knows friendship can bring him in, back up shooter who can give some time for either KD or Booker.
We will know what will happen once they already decide who they will add to their roster.
I do not think the Suns still need another scorer on their roster. They will benefit more though from a big man or a defender. Defense is a liability in all their stars. A good defender will complement the firepower that they have right now. Cousin is good but I would like to see someone that is a solid defender.
