Boston Celtics All-Star point guard Kemba Walker says Boston forwards Jayson Tatum and Jaylen Brown “are so talented it’s unbelievable.”

Walker, Brown, Tatum and Marcus Smart are in Las Vegas right now for Team USA training camp. Walker says it's been special to watch Tatum and Brown up close.

“Those dudes are so talented, it’s unbelievable,” Walker said, via Chris Forsberg of NBC Sports Boston. “I competed against those guys, what, four times a year? Might catch a few games here or there. End of the day, you don’t see them every day. You know what I mean? For me, to be here and see those guys, and the way they compete and how much passion and love they have for the game, the intensity they have for the game, that’s special to me.”

Kemba Walker, Jayson Tatum and Jaylen Brown are the new Big 3 for the Celtics after stars Kyrie Irving and Al Horford left this summer in free agency.

Tatum has career averages of 14.8 points, 5.5 rebounds and 1.9 assists, while Brown has career numbers of 11.2 points, 4.0 rebounds and 1.3 assists. The Celtics are expecting big things from both guys next season.

Walker has career averages of 19.8 points, 3.8 rebounds and 5.5 assists in 605 games. He put up 25.6 points and 5.9 assists this past season with the Charlotte Hornets.
