I wouldn't say anything if the people above him were also undefeated, but they've taken losses. At a certain point, the people doing the ranking should trust their ability to watch the matches, otherwise, why are there even humans ranking these guys?
I'm not saying to put him #1. I'm saying put him #4 above the guys with losses who haven't looked nearly as impressive. Only KO and Carr proved it against world-level competition with similarly impressive results. And of course, I wouldn't say rank him solely based on that, but if you watch his matches, it's so obvious that having him at #7 is a joke.
