Here’s the Philadelphia Inquirer reporting on the 76ers and summer league:

Ronald Roberts Jr. aims to prove he’s a keeper.

An undrafted rookie free agent with the 76ers, Roberts came to the Orlando Pro Summer League with a chip on his shoulder. The power forward/center out of St. Joseph’s plans to give all he can on every possession.

“For me, this is a critical moment,” said Roberts, who finished with 12 points and six rebounds Sunday in an 84-73 victory over the Oklahoma City Thunder on the Amway Center’s practice court.

“I just want to show everybody what I’ve got,” he said, “just playing my heart out [to] make my dreams come true. Like I said, when I [went undrafted], I went to the court. . . . I just want to show these people.”
