If you thought LiAngelo Ball's dunk sesh at the Lakers practice facility was impressive ... wait 'til you see Zion Williamson's "hold my drink" response Tuesday.
The Duke commit -- clearly reacting to 'Gelo 'cause of the "dead legs" caption he shared -- nearly took down a rim trying to top the middle Ball brother's performance.
The first dunk: A self-lob, behind-the-back jam.
The second dunk: Another self-lob, left-handed hammer.
'Gelo's clearly got ups ... but yeah, we're givin' Zion the nod here.
Zion's got at least a year under Coach K before he heads to the NBA ... and 'Gelo might need a year in the G League before he's in the big show ... but maybe see you two in the real dunk contest in 2020??
