Despite playing three years of NCAA Division I basketball, Trey Murphy III had never been part of anything like what he witnessed March 27 in the Smoothie King Center. As New Orleans roared back from a 20-point halftime deficit to beat the Los Angeles Lakers, a crowd of 18,516 fans delivered a level of noise and excitement that made the 21-year-old wish to be part of that environment again, as soon as possible. The rookie forward and his Pelicans teammates will get that opportunity Wednesday, when they host the San Antonio Spurs in a do-or-die Western Conference play-in matchup, in front of a capacity audience.
