Former British and Irish Lions star Sam Warburton believes that Scotland is lacking the "killer mentality" needed to succeed as a top Test team. In a recent column and podcast appearance, Warburton criticized the Scottish team for their lack of ruthlessness and killer instinct. He recounted an incident where two players celebrated a win over Wales in a manner that he found arrogant and unprofessional, reflecting a cultural issue within the team. Warburton believes that Scotland's struggles to reach their full potential stem from a lack of hard edge and elite mindset.
