Frankie Edgar not realizing he was losing every exchange in which he caught Bendo's kick, and doing it over and over instead of trying to time it and counter. That was really disappointing.
Struve, well... Struve.
Totally, was a bad idea on Frankie's part. If your entire gameplan is based on moving and being elusive... Don't catch a kick and stand still so your opponent can punch you in the head.
