Flagg is projected as the No. 1 pick and Johnson as the No. 5 pick in the 2025 Draft by Bleacher Report's Jonathan Wasserman. Barring a trade or unprecedented fall, it is very unlikely that the Celtics would be in a position to select either player.

Cooper Flagg is more than likely going to be a member of the Dallas Mavericks next month. That's a statement, around this time last year, I would've thought was impossible and just minutes before the NBA Draft Lottery,

While his NBA fate was presumably determined by the NBA Draft Lottery, which saw the Dallas Mavericks get the top pick, Flagg still partook in testing at the NBA Scouting Combine in Chicago. In addition to testing, he also interviewed with teams, one of which was revealed to be the Boston Celtics, according to insider Kevin O'Conner.
