DC isn't fighting 'better than ever' he literally got beaten to sleep in his rematch with Jones. He couldn't make it out of the third round. Volkan had absolutely no business in a title fight, but the division is paper thin. Gus dropped DC like a sack of potatoes and took him to a gritty controversial decision. Regarding his heavyweight run, Roy Nelson has a losing UFC record. If you fought Roy Nelson in the UFC, you had better than 50% chance of beating him just by way of showing up. Everyone beat Roy. Mir, have a look at his record in the last 5 years. Bigfoot has been knocked out a cartoon number of times. It's an enormous step up in (heavyweight) competition for DC fighting Stipe. Blaydes would be a substantial step up from Roy and Mir.
