Jaylen Brown dunks on kid who said Ben Simmons is better than him

The Boston Celtics upset much of their fan base when they were unable to swing a trade for an established veteran and instead selected Jaylen Brown with the No. 3 overall pick in Thursday's NBA draft.

"He challenged me, and I just blacked out," Brown told MassLive.com. "He said, 'You ain't good.' He said, 'Ben Simmons is better.' So I said, 'All right, OK.'"
