In 1969 at the age of 21 Millward was given the captaincy of Hull Kingston Rovers and was also voted the supporters' player of the year for the second time as well as being honoured with the title of Rugby League Players No 6 "Player of the Year".
In the mid-1970s Hull Kingston Rovers had become a dominant force in the world of rugby league thanks in part to Millward's playmaking abilities.
