Watch how Jon Jones and Rashad Evans got to UFC 145 title bout (Yahoo! Sports)

With UFC 145 coming quickly, take an extended look at how the two main event fighters worked towards the title match. In it, Jon Jones admits that Rashad Evans is in his head. He's constantly thinking about Evans, how he's training, how he's improving, and how Jones can beat him.

But Evans thinks his knowledge of Jones is exactly what gives him the edge.

"I've got the advantage mentally, too. He's not 'Jon Jones unbeatable champion' to me. I know the real Jon, the nervous kid who would ask me to tell him how to dress, how to talk and how to fight. I know how he reacts when things don't go his way, how he can't handle it mentally," Evans said.
