Sheaf has always struck me to be à confidence player. It’s a viscous circle: when there is a potential shot on, he’ll more often than not elect to pass and more often than not the chance lessens. Result: fans vent their frustration and his confidence dips.
He seems to have improved his dallying on the ball and now needs to develop the self belief to just have a crack. Once he does, he’ll be a heck of a player.
