When they moved Williams they got what was widely considered the best possible haul in return. Now, it turns out that the players and picks they received (Favors, Kanter, etc....) didn't really turn out as well as we all hoped, but at least they received SOMETHING in return. If Hayward walks, it's losing an All-Star for nothing, zip, nada in return. It will take the franchise 5 years to recover.
