Like I said before, as a defender, yes he is. There were a good few times that balls came in over the top that were dealt with via a powerful header by Duffy. I can't/don't remember Webster doing that.
But – as I ALSO said before – Duffy is NOT a Potter player, because he doesn't look as comfortable with the ball at his feet or when taking the ball out of defence. But Potter's tactics haven't exactly been working anyway, so...
You'll no doubt argue that the goal was Duffy's fault, but then Webster has been responsible for a few as well :shrug:
