Presumptive No. 1 overall pick Cooper Flagg interviewed with the Celtics last week at the NBA Draft combine, an unexpected interaction between the former Duke star and Brad Stevens, Boston's president of basketball operations.

Celtics president of basketball operations Brad Stevens addressed the media on Monday. Here are five highlights from what he said.

Simmons wondered whether the Celtics should ship Porzingis off to the Atlanta Hawks in exchange for 27-year-old power forward John Collins, who is set to earn $26.6 million next season before becoming an unrestricted free agent. “John Collins was in one of my get-the-Celtics-under-the-second-apron trades,” Simmons said.

Stevens said the Celtics expect Porziņģis to improve over the coming weeks and that he will play for Latvia in EuroBasket, the quadrennial international championship series sanctioned by FIBA Europe. The competition begins Aug. 27 when Latvia squares off against Turkey.
