Joe Rogan is about as synonymous with MMA as a takedown. Unfortunately, something synonymous with Rogan is his biased commentary at times.
Rogan has been under a lot of scrutiny through the past years for his overly biased commentary but it's hard for fans to fault the guy. It's incredibly hard to not show a bias when Rogan knows/talks to many of these fighters when the cameras are off.
But in the world of professional journalism there's a time and a place to share your opinion; the main broadcast of a UFC PPV is not it. If the fighters on this list are ever involved in a close decision they can always depend on Rogan to talk them up to influence fan opinion.
