I kind of doubt it. Flagg seems to be well liked. And doesn’t appear to have that in your face mentality like JJ did. Plus it usually grows over time and great players aren’t staying at Duke long enough to be hated. As it is, people will see Flagg once - twice if they see him in the tourney - not 4 times plus the ACCT like they did JJ.
Also feels like a different culture in sports and CBB. Fans in general are softer. The offense police are always on the prowl. Used to be Duke fans just crushed opponents. Duke and Maryland. Of course with so many players in the portal every year, every team except a few look entirely different every year. I don’t know half the players at the start of the year each year.
Except for the few that know they can’t handle the NBA so make a career out of playing at UNC.
