Regardless of Tabs fitness, I can guarantee you we will be playing 2x 195cm players down there. (Take your pick from Jackson, Taberner Treacy or Amiss), and if you were also a defender that is 195cm or taller, you'd go to them first.Which is at least half of the games.
So the defenders go down to set up, they see Fyfe. Who else do they see in the Freo forward line that requires minding first?
I don't reckon tall guys will go to Fyfe, they'd nullify him in the air but not at ground level. It's why you don't see really tall defenders going to Heeney.
