Going by what we saw last year: Joseph Paulo and Terepo are 'middle forwards' (13 Jersey types). And Pauli will be used as an edge forward this year for us.
I also have a feeling that Radradra locked himself up a wing spot with his performances in the 9s. Yes, I know, it's ridiculous to draw any conclusions about real footy from a 9 a side comp, however he just seemed to show 'something' when given space to move, and will be a more than useful finisher.
Surely Ken Sio has the other wing spot sewn up? Personally I'd go with Morgan, he's played some very good games for the Eels on the wing in the past, and he has a bit of toe once he's going. [I also just don't trust Sio, although he was remarkably 'solid' last season] The thing standing against Morgan is that he doesn't tend to ruck the ball out of our own end after a kick, he waits for someone else. Sio is a workhorse in that area, and makes nice meterage - which is a huge part of a wingers game.
