Whakakiia te rerenga e whai ake nei: I tae atu a Duncan ki te huihuinga LIHG i te wa o te
1947 Ice Hockey World Championships, i reira i tono te CAHA mo te mohio ki tana whakamaarama hou o te amateur hei tangata kaore i kaha ki te mahi i tetahi hakinakina ngaio me te whakakotahitanga o te International Ice Hockey Association me te LIHG. I te hui nui o te CAHA i te tau 1947, i whakahe a Duncan ki te whakapiki ake i te tauhokohoko o te hockey hukapapa rangatahi me te tautoko tika o nga roopu e te NHL. Whai muri i te whakatinanatanga o nga kirimana a te CAHA mo nga kaitakaro rangatahi me nga kaitakaro matua, i whakaaro ia he mohio ki te semi-professionalism kore o te CAHA.
