After a week of mayhem, Thursday's NBA's Draft figures to play out at a decidedly lower decibel level at AmericanAirlines Arena. For now, silence appears the order of the day. Not only do the Heat lack a first-round pick, with that selection sent to the Cleveland Cavaliers as part of the LeBron James sign-and-trade transaction in 2010, but the Heat's second-round pick was sent to the Memphis Grizzlies at the mid-February trading deadline as part of the selloff of Dexter Pittman's contact in a salary-cap dump. Under Pat Riley's stewardship, such draft-day inactivity hardly has been rare, with both of last season's draft picks dealt, with the Heat eventually winding up with Louisiana State center Justin Hamilton in the second round as part of the draft-night trade that sent the Heat's 2012 first-round pick to the Philadelphia 76ers. Chet Kammerer, who heads the Heat's draft scouting, said Wednesday the team remains poised to make a draft-day move, believing numerous picks could become available. "We didn't prepare this year any differently than if we have had a pick," he said at AmericanAirlines Arena. "In fact, I think we've worked harder. When you have a pick, you kind of zero in on where your pick is and you probably focus in right there. We were told that we could possibly get late lottery, we could have one in the 20s, have one early second. So we approached this draft with as much effort." The difference, Kammerer said, is the Heat did not bring prospects in for individual workouts, instead attending group workouts held by other teams and similar group sessions staged by agents.
