Melvin Guillard has enjoyed some fine moments in a 50 fight MMA career, which dates back to 2002.

The 32 year old “Young Assassin” has enjoyed TKO wins over the likes of Gesias “JZ” Cavalcanti (last year) and Mac Danzig in 2013. His run in the UFC, which began at The Ultimate Fighter Season Two, was highlighted by a five-fight winning streak from 2010 to 2011.

2015, however, hasn’t been a year to remember.

Back in April, the fighter was cut from MMA World Series of Fighting, after appearing in only two bouts in 2014. The promotion’s president Ray Sefo described Guillard’s behavior as “unprofessional” — citing several instances of missing weight, among other issues.

“I’ve been a grumpy person for the last year,” the fighter admitted to MMA Junkie yesterday. “Dealing with different organizations and moving around.”

But Guillard got a new start last month with Bellator, and it sounds like he’s in a happy place.

“The financially side of it, the way that my contract is set up, coming from my mouth, it’s the best deal I’ve got in my MMA career in 22 years,” Guillard said. “I can’t be happier. I have a reason to fight hard, I have a reason to go out and give them 150 percent of me every time I go out. That’s what Bellator is going to get. They’re going to get the Melvin Guillard that was my early years of the UFC when I was knocking guys out in the first round.”

He adds that he hopes “to be with Bellator until I retire” — and feels he has “at least another ten years of fighting” left. His Bellator debut has not yet been scheduled.
