McGregor's coach told Ariel Helwani on Monday's edition of The MMA Hour that he anticipated Alvarez being overmatched in the UFC 205 main event. McGregor won by second-round TKO in the first-ever UFC card at Madison Square Garden in New York City on Saturday night.
"He seems like a great guy," Kavanagh said of Alvarez. "Solid fighter. But if we're just looking at skill sets, I felt going in ... that this was a massive mismatch. That's nothing to say about him as a person. Just skills wise. I really felt like this would look worse than the [Marcus] Brimage fight. But that style of fight."
McGregor knocked out Brimage in 67 seconds of his UFC debut back in 2013. On Saturday, he became the first two-weight world champion in UFC history. Already the featherweight titleholder, McGregor beat Alvarez for the lightweight belt at MSG.
Going in, Kavanagh said he felt like the fight would "look terrible" for Alvarez, because his wrestling game was "not very complicated" and he didn't have much to offer McGregor on the feet. Oddsmakers, though, felt like the fight was fairly even. McGregor closed as a flight favorite.
"I just felt you have to bring a hell of a lot more than that to the plate to trouble who I think is the best fighter on the planet right now," Kavanagh said.
The coach said he saw things go south pretty quickly for Alvarez, who was dropped twice in the first round. Kavanagh said he noticed Alvarez's corner go into a "panic" in the first round, screaming at the fighter.
"He seemed to be kind of almost talking to them," Kavanagh said. "It just looks like disarray. in my head I was thinking, this is gonna go bad fast."
Kavanagh said he saw Alvarez perhaps depart his game plan quickly. But he was impressed that the Philadelphia native was able to pop up after the first knock downs rather quickly, "like an accordion."
When that happened, Kavanagh said he feared that Alvarez would be a "zombie" like Nate Diaz, coming forward the entire time despite being hurt and rocked. But it wasn't to be. McGregor landed a wicked combination at 3:04 of the second round, flooring Alvarez and finished with punches on his grounded opponent.
When all was said and done, McGregor dominated all eight-plus minutes of the fight. He made it look easy in beating the man who was previously thought to be the best 155-pound fighter in the world.
"There's no wasted movement," Kavanagh said. "Every step is for a reason. Every feint is for a reason. Every movement of his eyes is for a reason."
Not that Kavanagh was all that surprised by the process or the outcome.
"Skillset wise, I just thought it was a massive mismatch," Kavanagh said. "And i will humbly offer the evidence of the fight as [something that] warranted that."
