LAS VEGAS (AP) — Cooper Flagg strolled into UNLV’s Thomas and Mack Center at 4:17 p.m. on Thursday, wearing Dallas Mavericks gear, bright white New Balance shoes, and an emotionless look on his face as he passed through security.

The No. 1 overall draft pick faces off against Bronny James and the Lakers in Summer League with broadcast available on ESPN and multiple streaming platforms.

Flagg's fans had plenty of energy, electrifying the jam-packed arena that went cheered loudest when he was announced as a starter.
