he's probably referring to the fact that dupreeh has carried them this map so far, people dont know that 5 matches are nothing compared to all what dev1ce did for Astralis in the past and especially recently.
they weren't though?? i remember like 2 triple kills. he had a middling performance. at least 2 other players have had just as much round winning impact. i'm not sure in which universe that was a carry.
