Now that the NBA's biggest stars routinely decline to participate, what used to be a can't-miss All-Star weekend event has turned stale. TNT revamps the dynamic in "The Dunk King," which offers 24 professional dunkers -- all non-NBA players, and none taller than 6 feet 6 inches -- the chance to leap from obscurity to celebrity and win $100,000. The pros, many of whom compete full-time in dunk contests for prizes that can range from $1,000 to $15,000, include brothers Chase and Jordan Kilganon, 5-foot-5-inch Porter Maberry, who won last year's competition, and Guy Dupuy, who sports a 59-inch vertical leap. The limited series airs during TNT's coverage of the Eastern Conference finals.
