Biggest threat to Jones at 205...

 a growth spurt.

 Pretty much. It's scary how good he is, he doesn't even realize it. He'll be so tentative early on and once he just lets it fly no one is even close to him. If he doesn't move up to HW by early 2013 there are going to be a lot of retirements from the old garde. 26 year old Jon Jones at 205 is a frightening, frightening concept.

I see him wrecking all the HW's as well.
