“Pop,” as he’s known, is very private, but he finally agreed to pop off on a phone call. He wouldn’t pose for a picture, however, explaining that he should not be the focus. He has spent 25 years in a dialogue about race with his teams. He took players to see “Hamilton” on Broadway, Ava DuVernay in L.A., the African-American Museum in D.C. and the National Civil Rights Museum in Memphis. He gave players copies of “Between the World and Me,” by Ta-Nehisi Coates.
