LiAngelo Ball is getting a co-sign from one of the NBA’s top talents … with Jayson Tatum, the Summer League standout is long overdue to have a spot in the league!!

The 22-year-old showed out during his time playing in Vegas over the past week — scoring 9.6 points in 17 minutes per game … with several incredible highlight plays.

We caught up with the Boston Celtics star outside Avra in Beverly Hills about Gelo’s string of performances … and he thinks Ball did enough to get him on an active roster for 2021.

“I think so,” Tatum tells us. “It’s only right, he’s put in the work. I’m sure he’ll find his way on a team.”

Of course, the middle Ball bro has had a long journey up to this point — he left UCLA in 2017 following his shoplifting incident in China … and ended up moving to Lithuania to play ball with his little bro, LaMelo.

Once Gelo returned to the U.S., he landed offseason chances with several NBA teams over the past 2 years … before earning a spot with the Charlotte Hornets this summer.

A lot of folks are hoping to see Gelo finally get his shot … and Ball himself even feels like he belongs in the league.

There’s more with Tatum — we also had to ask about his new teammate — Dennis Schroder — #0 tells us he’s stoked to have the guy join the Green and White … and thinks the guard will ball out and get PAID next season.
