Still can't believe Michael Johnson beat Edson...
Lesson I learned from Johnson / Ferguson is that when facing Barboza you have to go full Prime Wanderlei Silva Mode and put heavy pressure.
You can't give Edson time to set up his fast as fuck kicks.
When retreating or back peddling Edson usually relies on his hands to counter and rarely utilizes his biggest weapon (Kicks)
Edson is more then three fights I've seen has been rocked by his opponent that have thrown a wide looping right hook, not sure what it is but there is a hole in his defensive mechanics when dealing with the wide right hook,, perhaps a solid boxing coach could fix this very minor weakness that has caused serious issues on more then one occasion for Barboza.
Of course all this is easier said then done, but so far this has been the blueprint to defeating Barbz
