Franklin put in a poor performance at right tackle in the Super Bowl which was widely maligned by the club's supporters and the media, and has resulted in the 27-year-old being moved to left guard for the 2014 season.
He told reporters: "Initially, you get down on yourself when you hear you're moving from your position. I'm not a 'me' guy, but it didn't seem like initially it was a good situation for me.
"It had nothing to do with the team. I got mad at the world. I read an article and saw what fans were saying, that I had a horrible game in that final game.
"I took it the wrong way. When people started getting on me about it, I didn't take it constructively. I didn't listen to what my coaches were saying about it. I was listening to all the outside noise."
Franklin was drafted in the second round of the 2011 Draft by the Broncos.
