Too angry and embarrassed to sleep, Nuggets forward Danilo Gallinari must stare down a tough question: Did the pain of his NBA playoff experience help him grow, or expose him as a performer who shrinks in big moments? Ever seen a 6-foot-10 man disappear? Gallinari did in Game 7 against the Lakers, when he committed four turnovers but scored only a single basket, as Los Angeles knocked Denver from the opening round. Gallo was a zero. The hurt left an emotional scar. You could feel his humiliation from here to his native Italy.
