Four-and-a-half hours before tip-off Dwane Casey heads downstairs, to the basement of his three-story brownstone in midtown Toronto, and lowers the ironing board from the rack on the laundry room wall. The cover is baby blue with vertical stripes, a Christmas present from his wife, Brenda. She also bought him a new iron, a white T-fal, but he still prefers the silver Shark. After positioning the board on a narrow strip of brown carpet alongside his office desk, he grabs the steaming Shark and prepares that night’s ensemble: shirt, jacket, pants, pocket square. For the few minutes he guides metal over cloth, he is not the coach of the best team in the Eastern Conference and not the winningest coach in the history of the Toronto Raptors.
