At this point I think we've pretty much heard from everybody who was at the "Go Big" press conference in early September, also colloquially referred to now as "The Conor McGregor Show."

The "Notorious" fighter was in especially fine trash-talking form, directly slamming and insulting Chad Mendes, Jose Aldo, Rafael dos Anjos, Dustin Poirier and Donald Cerrone, and even taking pot shots at Luke Rockhold and his own countryman "Irish" Joe Duffy.

While at least one fighter thought McGregor's antics saved him from a "boring as shit" press conference, veteran fighter Josh Barnett wasn't especially enamored by the trash talk. Talking to Ariel Helwani on "The MMA Hour," Barnett said that while he didn't feel personally attacked by McGregor, others were being insulted indirectly and didn't call him out on it.

"It's crazy. He's sitting there talking about, ‘Oh Jose Aldo, you came over here and were given your championship' and all that. Right over there is Ronda Rousey, who was just given her championship. Just insulting the shit out of her at the same time, as he is trying to drop a bomb on Aldo."

Barnett said it's surprising more people haven't become annoyed at McGregor for these kinds of comments, adding it would "been awesome" if Rousey had confronted McGregor on stage.

"The biggest thing is he wants to speak his mind as much as possible. Right or wrong. Smart or stupid. He is just going to let it rip and pick up some hype whenever he feels the moment coming to him."

Despite Barnett's comments, Rousey and McGregor have had fairly positive things to say about each other in the past with the latter once saying he's "inspired" by the women's Bantamweight champion. He also stated Rousey would likely toss him on his head if push came to shove.

Rousey returned the love, saying it's been a joy watching him progress and mature as a fighter and as a man.

Barnett -- who battles Roy Nelson tonight (Sat., Sept. 26, 2015) in the UFC Fight Night 75 main event -- doesn't disagree that McGregor is a talented individual. He told Helwani that his performances inside the cage have been "fantastic" and have impressed him, it's his antics outside the Octagon that can certainly alienate fellow combatants.

He added that the obnoxiousness of McGregor seems to be rubbing off on his fan base, who are emboldened by the Irishman's trash talking personna.

"The McGregor fans, some of them are on another level. They think that because Conor is so brash it gives them license to say any inane, obnoxious stuff that come into their head. And it's like, well, it's great to have heroes and even to be inspired by somebody who's polarizing or even the nicest person in the world. But remember, their accomplishments are theirs. Go live something for your own life."

Well, to be fair, there are a lot of "drunk dummies" who watch MMA.

As for McGregor, in defending his trash talk at the Go Big press conference he said: "People are always saying about 'the talk and I talk and I talk and I talk'. But, guess fuckin' what? I back it up! I back it up!"
