There's some truth here but it depends where the fans are from.
It's no secret that "Good ol' boys" from the rural/non-urban parts of Georgia/SC/NC are not thrilled with "Yankees" moving to the south and that includes Cuse joining the ACC.
You'll have zero problem being a New Yorker in 2018, living in Atlanta, Greenville, Columbia, Charleston, Charlotte or Raleigh but if you venture outside of the cities and into the burbs/rural areas of those states, the anti-Yankee sentiment is still very real.
