Well Smith has presumably done his research. Noakes was born and brought up in NZ so I can only assume he has an English parent/grandparent.
But no, no one cares because he'll struggle to make the Irish starting team let alone an England one.
I remember when Yarde announced he was leaving Quins some people from Irish made grumpy noises because he was leaving despite all the squad investment they had told us all they were doing. I wonder if they sat him down and said 'Now Marlon, we've got a lot of great players coming next season to play alongside you. This one guy, Chris Noakes...' at which point Yarde drove over to the Stoop to sign a contract.
