LAS VEGAS — After playing five basketball games in less than 48 hours, Dereck Lively II slung a gym bag over his shoulder and headed for the exit at the corrugated metal warehouse where he had spent much of the last three days performing in front of N.B.A. scouts.
Before Lively reached the door, though, he was handed a tablet. Tap here, he was told. Just like that, a 30-second highlight video unfolded on the screen of Lively smiling, dunking, mugging, running and dunking some more, all during the camp.
“This is sick,” said Lively, his eyes lighting up as he watched.
