I don’t know if Ned would have been a builder Hand like Septon Barth or Ser Osmund Strong, given his focus on the royal debt. And I don’t know if he would have been a particularly legislative Hand.
If Ned had understood his role better, I think he would have been a reformer Hand much in the vein of his forefather Cregan Stark – wiping out corruption at court and then going home.
And I think Robert would have been bored stiff by infrastructure planning, but would have really enjoyed ribbon-cutting ceremonies.
