Machida won the 1st round in my opinion. I know it doesn't matter, but I think that was the first round Jones lost in the UFC, and quite possibly in his whole career.
Hendo would not do anything to Jones. Just let it be known, I might be the biggest anti-Jon Jones supporter here, and he would go through Hendo if he avoids his right hand. Hendo is very predictable, and Jones is known to study tape of his opponents very closely, and he would use that against Hendo easily. Fizzy is right about Hendo's wrestling too, I really haven't seen Dan use his Olympic wrestling at all in the UFC. Dan's good in the clinch, yet Jones is great in the clinch. Hendo only has a 52% Take down percentage in the ufc, which is nothing that an Olympic wrestler should have (Jones has a 64%). Hendo's TDD is decent though at 67%, yet Jon Jones is at 100%. Also, Hendo's cardio is not good, and if this fight gets past the 2nd I say (Hendo getting tired after the 1st is a little too far) than Jones will win easily. Hendo needs to go for big shots early in the fight, and rock Jones.
Overall though, Jones got hit, because Machida was faster in that fight. I only see Jones losing to someone who is clearly faster than him, and off of the top of my head I only see Rashad Evans being able to do that (Phil Davis is fast, but is really overrated in my opinion.) Hopefully Rashad runs through Davis, and is next in line for Jon Jones.
