Quade at 12? Or do you mean if Quade's at 10, the other 2 will fight it out for 12, which is what I think you mean?Don't mean to be a killjoy but isn't this all pretty pointless.
As long as Barnes, JOC (James O'Connor) and Cooper are fit all players mentioned are going to struggle to get time at 12. Cooper at 12 is a better option over many of those mentioned.
Maybe so, but 2 of them aren't fit and may have a tendency to break again. QC (Quade Cooper) has a long way to come still to be match fit and in form. More than likely other candidates will be called upon at some point.
