Edgar did what he had do to in order to win: move a lot, use his speed in combo and circle to avoid Bj's big hand. I think that the prodigy just didn't take him seriously and got shocked by his speed and audacity to throw him on the mat. Personally I quite liked this fight, it was not explosive but there was lot of good tactics involved and though he was the smaller guy, Frankie did the hell of a job.
