bika is tough as they come
Kevin Johnson is certainly a step up on what Joshua has faced thus far, he's fought Vitali Klitschko, Fury and Chisora and none of them stopped him in fact he's never been stopped. He is well past his best though and has lost his last 3 fights.
As long as Joshua is prepared for 12 rounds he shouldn't have a problem just don't go trying to do a David Price against Tony Thompson and try bombing him out in 2 rounds then gas yourself!!
Thought he only gave up the belts because he didn't want to defend and wanted to fight someone else?
