West Coast Eagles Premiership winning midfielder Elliot Yeo has won his second Fairest and Best award in consecutive years, but the humble player puts his success down to a coach who's leaving.  Yeo says any improvement he has made over the last few years has been because Sam Mitchell has put the hard yards in.  "There's still plenty that I feel can give and there's still parts of my game that I've got to work on. I've worked closely with Sam Mitchell this year and it's going to see him go," Yeo told 6PR.
