Id comfortably have fisher as the worst defender out of anyone who has player there in seniors for us...but outside of newman with ball in hand he has been the best. yes, even better than saad.Probably not Kemp or Saad. But you could make an argument for the other two. He's also naturally smaller which means he's never gonna be a physically astute defender. Will have to make it up with intent on and off the ball (e.g. Noble, Daniel, Bowey).
it's a tradeoff and my personal preference is too have no weaknesses in the back 7.
