I do understand the argument that Chael and Dan have totally different stances and it is a completely different training camp and fight, stance wise. But Chael is still, as everyone is saying, an out of shape and unprepared fighter while JJ is top 3 pound for pound with a full training camp.
Now, JJ has to fight Machida most likely, which is a MUCH MUCH more dangerous fight for him, especially without a full training camp, while Machida was already thinking of and planning on fighting JJ after 151. If Jon loses against Machida, it's going to be a lot worse for him than if he lost against Gangster Chael, who most people would have called a showman anyways for coming up and "saving" the card.
Consensus on twitter is 99% hate for JJ, especially from his fellow UFC fighters (except for Ben Henderson, who made some dumbass comments), and ESPECIALLY from the undercard fighters who are now left with many bills to pay.
Jon Jones used to be a fighter who I supported, but not at all anymore, unless he releases a statement that convinces me otherwise, which I highly highly doubt. Chael appears to be more badass now, and basically talked his way into the fight. Sure he didn't earn it, but I'd LOVE to see the fight still, even if it's Jon Jones taking Chael to school with elbows and kicks. I'd expect Silva/Sonnen II all over again.
Edit: just saw Chael's interview on Sportscenter, I like him more now. He did kiss Dana's ass a little, but I like it when Chael speaks. I think he called JJ a brat about 6 times.
