Best: Joe an attitude adjuster

Joe Schmidt’s "ruthless" selection policy has forced Ireland to shed mental weaknesses that were costing victories, according to Rory Best.

Hooker Best admitted Ireland may well have failed to close out Saturday’s 26-23 victory over Australia in previous campaigns.

The Ulster front-row conceded Ireland suffered “mental switch-offs” in a 32-15 defeat to Australia and the last-gasp 24-22 All Blacks loss in November 2013.
