Until JJ fights at HW i cant take him seriously as a HW. Someone like Overeem would snap him like a twig, and Jon dont have the power to put him away. Thats the reality of Jones at HW. So many of his advantages are neutralised. Even people like Hunt and Rogers, hit hard enough and are used to being hit hard enough, that it wont help Jon as much as he needs it to, that hes a better all round fighter.
