Roy Williams And The Importance Of Practice Posted Feb 23, 2016 Roy Williams is no Allen Iverson — he wants to talk about practice. UNC’s starting lineup has been a revolving door of different players in the past few weeks, but he said the decision about who starts isn’t really up to him. “I don’t have a plan. Many people think coaches make the decision who starts, and I think players make the decision by how well they play in practice.” (Chapelboro.com)
