I dont think Dunk did to my mind he pulled out and as a result Wilson threw himself over him. At least the opinion and discussion helps kill a boring TV night on a Sunday.
However you look at it the ref made a mistake in not giving it. I am the only one who thinks he also possibly made a mistake with the one he did give and was conned by Wilson.
Unless it is a direct strike on goal or one on one there is no advantage greater than giving a penalty so in most cases advantage shouldnt be played.
Certainly not cos he might have a shot
