I see this argument being used atleast once in every Cormier thread and it shows how foolish and silly most posters are.
At this current weight Cormier is not as strong as he was at HW. The dumbest possible thing a human being could say is that "Well uhm, he threw 265lb Barnett, how can he not throw around 205lb Jones? Hmmmm?". This is not the same guy that overpowered big heavyweights. He did not just cut fat to get to 205, he lost some muscle too. DC also has to follow a strict diet due to past issues with this weight, so he is most likely weakened by that as well.
He's still strong enough to man handle a much smaller 43 year old man, sure. But not against a primed, wide, 6'4 accomplished NCAA wrestler in Jones. A guy who is much, much better at defending takedowns, scrambling, getting back to his feet etc. than anybody else Cormier has faced so far.
Use your brains and learn about weight classes. Don't be so childish.
