Suga doesn't like Bones. He thinks he's cocky and disrespectful. He has repeatedly called Jon fake and questioned his character. Also Evans said that Greg Jackson training Jon Jones was the main reason he left that camp. Greg says he still considers Evans a close friend but Suga said he hasn't spoken to Greg in almost a year and will never train under him again. So while there is hype just like all the big fights, I think there are some hard feelings as well.
