I think its because over the past few years we seem to lose the arm wrestle over the course of a match and therefore, we need more punch from our wingers. Okonbur and DWZ provide way more metres and aggressive running in the first to hitups, whereas Meaney struggles to gain solid metres. I say let Meaney play Fullback in CC and then if there is an injury to Corey Allan, he can come in (although i would actually prefer Baz to give Avo a chance at full back if Allen got injured and Burton has the number 6 locked down). In the meantime, i believe Avo at 14 will be good for his development (let him rove around the ruck like a Craig wing or Papenhauzen before he was fullback)
