Stephen A. Smith was right all along – at least, according to him.

In an interview Tuesday, UFC welterweight Donald Cerrone told ESPN he wasn’t mentally present for his January fight against Conor McGregor at UFC 246.

“Donald showed up,” Cerrone said. “‘Cowboy’ wasn’t there. Wrong guy showed up. I couldn’t get going, couldn’t get excited, couldn’t get fired up. (I) didn’t want to be there.”

Wednesday, Smith took to Twitter to write a “told you so” tweet to all of the critics who said his comments were wrong or out of line. In the ESPN pundit’s eyes, Cerrone’s recent comments proved his point.

“I’m (curious), so all you MMA folks — who I profoundly respect — am I off my rocker now???” he wrote. “When you’ve covered sports intimately as a reporter for a quarter-century, you see things sometimes. I respect the hell out of (Donald Cerrone), but he just wasn’t there that night.”

Since UFC 246 featured the return of McGregor, Smith, as one of ESPN’s heavy hitters, was brought in for the special occasion. After McGregor blitzed Cerrone (36-14 MMA, 23-11 UFC) in just 40 seconds, Smith weighed in during his appearance on the ESPN+ post-fight show with Michael Bisping, Chael Sonnen and Jon Anik.

“I’m quite disgusted,” Smith said. “Let me be very, very clear: I’m honored to be up here with you guys. I’m a spectator watching the sport. I expected to see more than 40 seconds. I predicted McGregor was going to win this fight inside of two rounds. I thought he would take him out.

“Here’s the deal: 15 seconds in, ‘Cowboy’ Cerrone was done. He got hit with those shoulders in the clinch and he was done. It looked like he gave up. It was just an atrocious performance on his part.”

The comments led to a huge back-and-forth between Smith, media, fans, and even UFC commentator Joe Rogan. On an episode of his podcast “The Joe Rogan Experience,” Rogan ripped Smith for his comments.

“That’s a bad look for everybody,” Rogan said. “It’s a bad look for ESPN, it’s a bad look for him, it’s a bad look for the sport. There’s other people that can do this. … We have plenty of people out there who understand the sport. There’s plenty of them. … Stephen A. Smith is really good at that stuff. But it’s not the place for MMA. It’s just not the place. It’s not the same thing.”

Rogan’s comments got a quick response out of Smith, who posted a video to social media shortly thereafter.

“You don’t know me, so I’m not going to knock you for speaking out the way you spoke out without calling me,” Smith said. “I don’t care about all that. I respect where you’re coming from. You’re just wrong on this particular one, and I’m telling you you’re wrong.”
