Petts still has some significant upside IMO.
You could almost see the "click" in his head (when he is not punching himself
) under Wallace's gameplan and structure.
Could be a potential 50 goal a year player if improvement continues.
Still needs to work on the defensive side of his game and contribute some body pressure when tackling.
Perhaps the change in number is an omen ? Almost double the number & double the output !
