Coming off the bench in the second half in Pretoria, Mo'unga proved to be the All Blacks' saviour, slotting a conversion after the final whistle to steal the win after his side had been 30-13 down to the resurgent Springboks.
With Barrett having moved to fullback to accommodate Mo'unga's inclusion, debate has begun to arise as to whether or not the twice reigning World Player of the Year stay in the number 15 jersey, allowing for both stars to play at the same time though.
