Lancaster's tenure as head coach has been praised for the overhaul and reformation of England's squad culture, which had resulted in much media attention to the team's off-field antics during the 2011 Rugby World Cup, which immediately preceded Lancaster's reign. Lancaster has demanded that England's players be good role models, and as such has excluded players from various squads. Examples of this policy include Danny Care's exclusion from the 2012 Six Nations Championship, and Manu Tuilagi's omission from England's 2015 Rugby World Cup preparations. However, Lancaster's team selections, particularly at centre, and his failure to select or develop a specialist openside flanker for England have been criticised.
