Honestly, Ariel's not perfect but in my opinion he's been the face of MMA media coverage for years and whatever peoples' opinions are on him I do believe he is and has been the best MMA journalist in the sport by a noticeable margin. He's for the sport, for the people, for the fighters. I feel like the Brett Okamoto's of the world come off as "for the UFC" and are overall just really bland and "company man" in their coverage. Ariel isn't owned by anyone but the sport and his truth. He asks the hard questions and like a journalist who's in love with what he does, he digs to find the truth. That being said as far as instigating fights between the fighters, Ariel also tends to at time lack awareness in interviews or leave his filter at home so much that he asks really abrasive, insensitive questions and like with anything else he asks, he's usually persistent about getting his answers even if the interviewee tries to brush it off and give him the sign to back off of it. To answer TS' question though I haven't personally ever seen Ariel get caught in some sort of lie but I also haven't watched every MMA Hour episode or seen his entire body of work.
Didn't mean for that to come off as a Helwani fanboy post but I just think that history will remember Helwani as "the guy" for MMA media coverage. Idk if he'll wind up being the Howard Cosell of the sport like he said he'd like to be considered one day but as a journalist he's excellent in my opinion and I think as the years have gone by and the whole UFC/Dana vs Ariel thing happened (which ultimately went down because Ariel did his job as an *independent* journalist and the UFC let the Brock Lesnar return leak which imo is more their fault than his, like it's a journalist's job to discover and report the news/happenings) he's gotten amounts of guff that he doesn't deserve relative to what he gives us, the fans and how much he obviously loves the sport and covering it as well as the fighters. Like you can tell how passionate he is about it. You want those kinds of journalists in the sport imo.
