THIS is the beginning, not the end. One stage of James Tavernier s Rangers career is over, but another is only just getting started. The seasons of defeat, disappointment and despair are behind the 29-year-old now. As he looks forward to the next three campaigns at Ibrox, he does so as a champion. On Saturday, he will hold aloft the Premiership silverware for the first time. Rangers decade-long wait for the trophy is over and a chapter in their history can be closed. Matt Polster knows what that status will mean to Tavernier. He had been with him on that journey during Steven Gerrard s first two terms and seen the efforts that had gone in to deliver a title as significant as 55.
