#3 Mark Wahlberg
Mark Wahlberg has become a massive movie star enjoying successes like The Departed and Ted coupled with terrible yet financially successful movies like the Transformers series and Ted 2. He's one of the top dogs in Hollywood and has thrown his support behind Conor McGregor.
Despite being an American, it probably has something to do with his Irish heritage considering he's a native of Boston which has a notoriously large number of people with Irish blood in them. It'll be interesting to see if he was able to pass on any tips he gained about the boxing business from his time making the movie The Fighter.
Here's what Wahlberg had to say about Conor's chances against Floyd Mayweather Jr:
But Conor, I think is a very different kind of fighter. I don’t think [Mayweather] has the power to knock out McGregor.
