The UFC has continued with its progression into being recognized as a mainstream sport with developments like the Reebok sponsorship deal, their shiny graphics package and their new anti-doping policy, among others. And while it's been nearly two years since former UFC welterweight champion Georges St-Pierre competed in the UFC, he believes some of the changes could be for the better of the sport.

"This is the way it needed to be a long time ago," St-Pierre said of the UFC's attempt to clean up the sport by partnering with the United States Anti-Doping Agency (USADA).

The French Canadian was one of the staunchest advocates of a cleaner UFC back when he was fighting, and cited PED use of other fighters as one of the reasons he stepped away from the sport.

"I said it for many years, I just didn't come out. Ask anybody who knew me in the UFC, I said it for many years," St-Pierre told Yahoo Sports.

"I don't judge people why they do it. Some guys have a family to feed. It's not about the individual. If you accuse one individual, it's not going to change anything because another one [will come along]; you need to change the system.

"And that's why I'm very happy now, the UFC changed the system and we'll see what happens in the next few months. But if it really does happen like they say it's going to happen - they put these guys in public - thumbs up.

As noted by Yahoo Sports, under Nevada's new laws, a first time offender is subject to a three-year suspension and a fine of 50-70 percent of their purse. The second offense merits a suspension of four years, and a fine of 75-100 percent, while a third would result in a lifetime ban and a 100 percent fine.

"I believe that if they really do what they should do, there will be a lot of change in this sport. You'll see some of the stars falling. You'll know what I mean - if it's done right, you'll see," St-Pierre said.
