Second-year Boston Celtics forward Jaylen Brown will host a party in the spirits of good ole' clean fun for those under 21 years of age at an undisclosed location in Las Vegas.

As the Summer League rolls out and players make the best early impressions on their respective coaching staffs, most rookies and some second-year players can't enjoy the Sin City life at its fullest, making this the perfect opportunity to mingle with each other and find mentorships with former players and people around the league.

“There are a lot of young guys here, and there is nothing to do in Vegas if you’re under 21,” the 20-year-old Brown told Marc J. Spears of The Undefeated. “I just want to do something. Hang out, talk to them. Build relationships. I’m not 21. [Celtics teammate] Jayson [Tatum] is not 20. A lot of the draft picks are young.” ”

“I’m going to let them bring whoever they want. Food is on me. Everything.”

Brown has reportedly spent $5,000 of his own money to host this party — so far the top five overall selections in the draft have confirmed attendance, along the likes of Jonathan Isaac, Malik Monk, Harry Giles, and Justin Jackson.

Some second-year players that will join are Yogi Ferrell, Marquese Chriss, Brandon Ingram, and Rookie of the Year Malcolm Brogdon.

The non-drinking event will feature Executive Vice President of Strategy and Development for the National Basketball Players Association (NBPA), Chrysa Chin; Hall of Famer Isiah Thomas, who mentors Brown; and rapper G-Eazy.

“I feel welcomed,” Chriss said. “He’s one of my friends. It’s just showing a leadership role with him reaching out to other players to bring them together for this event. I want to come to it just to hang out, build relationships, talk to people and enjoy myself.”
