Yehp was a pure stopper which you could be 5+ years ago. Slowly over this time he's had to add more dimensions to his game that being able to drift off take marks as the 3rd tall coming in or spoil but more importantly provide run and rebound whilst hitting a target. Ideally you want every player in the back 6 to have that ability.
That's where the modern game is.
Tell that to Hamling Grand Final day, a pure stopper or a tagger are still valuable players if you have the right balance elsewhere.
