Who has Jones knocked out that makes you presume that he can finish the baddest man on the planet via KO? Cain is really strong, a natural HW, he held his own with brock in the wrestling game and even took him down, Jones is great, but he had trouble when he got pressured by DC. I think a lot of people are making some wrong conclusions based on the fact that he was able to wrestle with Cormier, he is still the same guy who couldn't take Gus down and got taken down, he is still the same guy that couldn't hold Glover down.
Cormier is not nearly as dangerous as Cain on the feet, his striking is not as fluent and he doesn't have the same power.
