Cooper Flagg Player Card Profile

Dallas Mavericks

Flagg already feels bigger than a typical rookie story. Dallas has put real creation and defensive burden on him, and the market can already picture the franchise-face version of this. The upside is enormous, but you only want exposure in lanes that can survive the first big cooling-off period.
