Whakaotihia te rerenga e whai ake nei: I ngaro ia i te whakauru mo te kapa 2014 Six Nations ahakoa te tini o te whakapono kaore a Scotland i te taha o te taha tuwhera. Whai muri i te whakatuunga o Vern Cotter hei kaiako Scotland, kaore a Barclay i whakauruhia ki tetahi o ana roopu Scotland i te tau tuatahi, tae atu ki nga Whenua Ono tuatahi a Cotter. Heoi, i kowhiria ia ki te kapa whakangungu 2015 World Cup whanui, ana i whiwhi i tana kapa tuatahi mai i te 2013 i te tukinga whakawera tuarua ki a Itari i Akuhata 2015. Ahakoa i mahue i te kapa whakamutunga o te Ipu o te Ao, i whakaurua ano a Barclay ki te kapa Scotland mo te
2016 Six Nations Championship a ka tiimata i nga keemu tuatahi e wha i te taha matapo, ka eke ki te whakamatau i te wikitoria ki Itari.
