I thought i read somewhere that he simply is not eligible. I bloody hope not. What i dont understand is how good must the Fly Halfs be that we have got to keep him out of the picture, he is supposed to be a gem. Sadly under Gatland being ultra-skilful is not a guarantee of selection. Sam Davies should be brought on over the next year or so. Former Junior World Player of the Year is now producing at the top level, i think he will overtake Biggar in the next two years if given the chance, he is properly gifted.
Any player can qualify on residency. It will be the only way he will, but he can.
He can't go to the JWC though as he's not eligible yet mind, but he can play 6N U20 rugby. Not at all weird, right?
