On Connor McDavid day (also known as the 2015 NHL Entry Draft) Brad Treliving made a shocking move that has been his crowning achievement thus far as General Manager of the Calgary Flames. By trading just the 15th, 45th and 52nd overall picks to the Boston Bruins, Treliving acquired Dougie Hamilton, who was just 22-years-old at the time. Hamilton was already with 3 seasons of NHL experience and was coming off a season where he was a top pairing defenseman with more than 40 points. Within days, Hamilton was signed to a six year contract, significantly altering the landscape of this Calgary Flames hockey club.
