Conor McGregor recently spoke to Severe MMA about the UFC's signing of CM Punk. Overall, his take on the situation seemed pretty focused on the positive, business end of things. He told reporters that "I don't have no problem with it. If you bring something with you to the table, you get a seat." But that doesn't mean that he sounded 100% comfortable with the idea of letting an "an amateur come in and do it in the pro game." Most notably, he focused on what he felt was obvious trepidation on the part of CM Punk in recent interviews. (transcription via MMA Fighting)
"CM Punk? I don't know," said McGregor. "Listening to him speak, when I heard the broadcast announcement I saw a man afraid. Like he signed up for something he didn't want to be. When the shin bone cracks the body or the elbow cracks or the heel cracks... It doesn't get much more real than that. Personally, I don't think he should be in this league just yet, but again, you bring asses to the seats, you bring eyeballs to the screen and we will give you a shot."
If nothing else, CM Punk still seems awfully uncertain with just what direction his MMA career will take, including camp and weight division. I"m not sure that that comes down to fear, but it's not exactly an illogical conclusion. Even Punk, himself, expressed some fears about going to a camp in which fighters might actively look to injure him, saying, "I don't want to step into a facility where there are people who have these negative feelings towards me and begrudge the fact that I've gotten this opportunity." That seems like common sense to my eyes, but people who fight for a living aren't exactly known for avoiding confrontation.
