"The Young Assassin" attempted to go back to Jackson-Winkeljohn Mixed Martial Arts, a place where his career once flourished, but was denied a spot with the tightly-knit fight team after his legal troubles (and a group vote) halted him at the door.
A move Melvin described as "a slap in the face."
So what prompted the fiery lightweight to leave sunny Florida and head to the rocky scenery of Colorado in the first place?
Melvin detailed the split on his recent appearance on "The MMA Hour:"
"I have a lot of reasons, but, if I had to stick to identifying the main reason, it's because obviously I wasn't winning there. I wasn't as successful as thought I was going to be. I was 5-1 with Jackson's and then I got there and I was like 1-4. My career took a little bit of a downward spiral. It's not that they don't have great coaches. They have a wonderful staff of killers, you know what I mean? Coach Henri is an amazing Dutch kickboxing coach and coach Mario Sperry is amazing himself. But, my chemistry with the team, I just wasn't vibing with the guys, you know what I mean? I like to do things a certain way. I'm my own boss, I don't like people telling me what I need to do. I don't mind if you offer your opinion, but, when it becomes to where I feel like I am working for you and you're not working for me, then it becomes a problem. It started being like that down there. They started doing attendance and tardiness. Man, this isn't the third grade. This is a professional sport and I'm a professional athlete and If I want to spend my off time playing golf and enjoying life with my wife, then that's what I'm going to do. I don't want to feel like I am obligated to go into the gym 365 days out of the year. That's just not how I roll. I've been in this sport for 17 years and I have had my times where I am a gym rat, but, it's not just my lifestyle anymore. I can still get the job done with doing an 8-10 week camp. But, that was part of the reason why. I love those guys and I do miss them, it just didn't work out for me down there."
Melvin shot down any theories that he is "un-coachable," saying he is one of the "most coachable guys" around and loves learning, but being "obligated" to be in the gym on his days off is just not his thing.
He also briefly touched on his ongoing legal issues in which Guillard said he was "jumped" by a group of individuals at an Albuquerque night club. A fight in which he says he never threw a punch, but is now being taken to court because one of the guys that assaulted him was hurt during the melee.
Guillard revealed he left all of his luxuries back in Florida to train with the Grudge Fight Team, a place where he already has chemistry with the coaches and fighters. "The Young Assassin" is currently living in a basement and sleeping on a twin bed cot with just a 10-inch television set to keep him company in preparation for his upcoming bout against Mac Danzig at UFC on FOX 8 in Seattle, Washington on July 27, 2013.
Looking at his next bout as a do-or-die situation, Guillard promised a knockout victory over Danzig in order to keep his spot on the ever-thinning UFC roster.
Can he deliver on that promise with the help of his new team?
