Who was better: Chamberlain or Russell, or Magic or Bird? Cohen, a fan and sports historian, rates the best centers, power forwards, small forwards, shooting guards, and point guards across five eras of professional basketball (“Set Shot,” 1946–60; “Superstar,” 1961–75; “Bird/Magic,” 1976–90; “Slam Dunk,” 1991–2005; and “Free Agent,” 2006–12). The five best—plus honorable mentions—are ranked with justifications. For example, Cohen uses statistics, championships, honors, and reputation to show why he selected Hakeem Olajuwon ahead of Shaquille O’Neal, David Robinson, Patrick Ewing, and Alonzo Mourning. Recommended for all libraries with a sports collection, suitable for circulation.
