If Sac ownership refuses to trade Cousins, and wants young, developed, low cost players, I can see Ainge trying to trade them AB and our 16th pick for their pick.
But I see Danny trying to trade picks with Charlotte, and then trading that pick and a player for a higher pick. I see multiple pick trades happening because it would be more enticing for a team with a higher lottery pick. I can imagine any number of different trades with different players and picks being traded. I really do not think that anyone is off the table.
