What team did Cooper Flagg root for growing up?

Cooper Flagg was born in Newport, Maine, on December 21, 2006, and went to Nokomis Regional there before moving on to Montverde Academy in Florida. He explained his Patriots allegiance in an interview Sportskeeda reported on December 10, 2025: "I was a Patriots fan growing up just 'cause that's the closest one to Maine, but I'm not a huge football fan in general," Flagg revealed. The reasoning is geographic, a Maine kid picking the nearest NFL team, and it is his own account.

The Patriots won Super Bowl XLIX in 2015, the year he turned 9, Super Bowl LI in 2017, when he turned 11, and Super Bowl LIII in 2019, when he turned 13.

Is Cooper Flagg a Cowboys fan now?

Sportskeeda reported the same day that Flagg said, "I'm a Cowboys fan now." The "now" fits his situation: the Dallas Mavericks took him first overall in the 2025 draft, and he has played in Dallas since 2025. Sportskeeda has him as a current Cowboys fan as of December 10, 2025, and the fandom dates from 2025, so it is an adopted rooting interest rather than a childhood one.
