Cooper Flagg | Swish Theory
Introduction Duke’s freshman, the top recruit in the nation playing above his age at just recently turned 18, has taken on mega offensive usage for the Blue Devils. While his efficiency has lagged given this significant change in role, the overall team impact is still there (Flagg is top ten in...

Cooper Flagg is best when roaming on offense (much like defense, which we will get to shortly), attacking the rim hard in transition, picking up putbacks, or just generally finding the ball in space. But he has shown advanced craft for a player of his size in developing as a driver and with shooting upside as indicated by a very strong free throw percentage. Given his athletic tools and measure of premium, dribble-pass-shoot skills at 6’9”, Flagg’s upside is a top 20 offensive player in the league.
Flagg is likely to be a very good on-ball defender, perhaps an elite one depending on where his strength ends up. He is most threatening one-on-one for his steals potential, as his man has to be extra cautious when attacking. Opponents have only made 2 buckets on 11 attempted iso possessions against Flagg, and only 22% on all attempts before Duke.
With his shot blocking, thievery, and on-ball defense likely to translate at 6’9”, it would be surprising if Flagg never made an All-Defense team. That puts him squarely in the top 10 for NBA defenders.
