Kevin stopped trying to win a long time ago and only fights to survive. Wlad should give him a chance with a 99/1 split (all he deserves). I think he may be the only one who can do it, with his huge one punch power.
He didn't stop trying, his old management screwed his career. Taking too many fights on short notice (Fury, Chisora, Hammer on-and-off) and placing him in Prizefighter (which KJ should have stayed far away from). Now he is stuck with just being a stepping-stone for prospects--type of boxer.
Johnson has a lot of talent, good reach, excellent chin, but needs to train very hard.......................if anyone knocks Johnson out it would be Vlad...........................but Johnson is there to survive...............he really could have been a good heavyweight, a top heavyweight............
I agree with Farmboxer, Johnson could have been a perennial contender but he just shows up to survive/take at least damage as possible. Not many are capable of knocking him out, his defense is very good and his chin is solid. Wlad is more than capable of doing it, Parker, Price, Povetkin and Wilder have a chance as well.
