Edmond sends his left hook sailing over her head so she doesn't have to duck. You're supposed to actually aim for the head so the student is forced to defend. Edmind is basically letting Ronda flail away with poor form, without any correction. There are many other video examples of his sh*tty padwork, even in the countdown videos for UFC 207. Bonus points for those who can identify all the other glaring errors in this so-called "padwork."
