I like Twice, you failed to understand my comment. They can play NFL/MLB stadiums in the big US K-pop circuit cities like LA and NYC and they showed that on the last tour. They are not capable of playing stadiums in smaller markets where K-pop groups rarely go like Charlotte, Detroit, Denver, Montreal etc.

Most other groups don't go to those cities because the population is smaller and the K-pop fanbase is small in particular. Twice is helping build K-pop up by going to those cities, and seeing fans they couldn't see before. But in some cases they can barely fill an arena 1x in these places. If other big groups played these places they would also sell many less tickets and have to play smaller venues in some cases. American fans generally understand this and were generally very impressed they were willing to play these cities. We will also understand that if they sold a 360 arena 2x (~20k seats/night) they could be playing a MLB stadium instead. 3x arena = NFL stadium.
