According to Murphy's travel team coach Dana Dingle, of the Long Island Lightning, he's also young for his grade.
"He just wants to get more physical and he's only 16," Dingle told Scout.com. "He's always played with the 2012 kids."
"Physically, mentally and emotionally he's not ready," he added. "Basketball he's got offers in 2011, but physically he wants to be to the point where physically he's ready to play as a freshman."
Murphy has plenty of colleges showing interest. Among the most involved are St. John's, Rutgers, West Virginia, Seton Hall, Pittsburgh, Arizona, Virginia Tech, Iowa, Iowa State, Virginia and Villanova.
Murphy, a 6-foot-8, 210-pound power forward, is currently rated as a three-star prospect.
