Johnson, what ever people think of him, has good/decent Boxing skills, Harrison, whilst most people assume he does to, doesn't imo, infact his technical skills are vastly overrated.
Johnson is a defensive minded fighter. That's just his style, so I don't blame him for going into a shell for 12 rounds against Vitali. I mean look what happened to Briggs, you don't wanna keep taking that kind of punishment for the whole fight. Johnson is a pretty good heavyweight and would whoop Audley
