This is just JR Smith being JR, and he seemed to channel his Marty McFly.
Smith, while jazzing the “Back To The Future” look up some, got everyone’s attention as he floated into the Q Arena on some type of futuristic looking hoverboard/segway, called the Hovertrax.

Sad thing about it, JR’s arrival lends no clue to how well he’ll perform tonight. He could shoot the lights out ... or stink it up.
