You can clearly tell Carter was not happy at all with the zone based on his words.
As a fan we definitely just want our teams to win............ but as a fan of UK I like watched a rival get blasted by its own former players for playing zone because it can help UK on the recruiting trail....... Its what you call trouble in paradise
I guess you can use the quote to fit whatever narrative you want. To me, this is nothing more than a player saying that he had to subjugate his game for the better of the team. Certainly nowhere near “blasting” his Duke experience.
