The 10 position is interesting. Many here have Cooper at 10, and I agree if he gets back to his best he is our best. However, his best is about two years ago, in my opinion he has a lot of ground to cover to get in front of Foley, who lacks Cooper's brilliance but is a solid performer that the rest of the backs may find easier to work off.
I agree that it's going to be tough for specialist wingers, with utility options like Horne, AAC (Adam Ashley-Cooper) JOC (James O'Connor) etc around, but if you were going to select between Tomane & Nayarovoro, my selection would be big T. I don't think either defend well enough at this stage, but I think the big fella is a more dangerous runner, and is improving rapidly, while I'm not sure Joe is.
Of course, Speight & Cummins are both safer selections for a specialist winger.
