Owen Roddy, Conor’s McGregor’s striking coach, admits Floyd Mayweather surprised them with his style in the clash last month at T-Mobile Arena in Las Vegas.
Mayweather, known for his defensive skills and counter-punching style, had a different gameplan for the night.
Instead of holding back and responding, he went straight at McGregor and pressed him from the centre of the ring.
Eventually, the Irishman got tired and was stopped on his feet in the 10th round.
Roddy regrets not being ready for that kind of strategy from Mayweather.
"I should have been aware of a game plan like that from Mayweather and that probably should’ve been done in camp.
"It’s hard to change things when you’re in the fight, so I’m a bit disappointed in myself that I didn’t predict that he would walk forward and let Conor catch him on the arms and walk him down," Roddy confessed to the MMA Hour.
"I honestly thought (Mayweather) was going to pop shots, sit back, work the shoulder roll and Philly shell. He did play that game for the first couple of rounds. Conor was having success with all of that, but unfortunately I didn’t have the stuff in place for the walking down strategy. We’ve learned from that."
Despite losing the fight, Roddy was overall pleased with his fighter's performance on the night.
"I felt the game plan that we came up with and the strategy we had for the first four rounds was really good. Conor was doing well. It was a tight fight," he declared.
"Conor was landing shots that we worked and he was landing them often enough.
"In my opinion, when Mayweather switched it up and he kind of walked Conor down with the hands high and elbows in and just kept walking forward and let Conor throw shots at the arms – when we saw that we hadn’t prepared for it. We tried to switch it up from rounds six or seven.
"When it’s that intense, and you’re constantly being pushed back, it doesn’t matter how fit you are. From nine and ten, Floyd managed to put Conor on the back foot for those two rounds and kept walking him down.
"I know from experience, when someone is constantly pressuring you like that and you don’t have a second to get a breath, fatigue sets in really quick."
Mayweather's approach came as a surprise for most of the people interested in the fight. Although he promised to be aggressive and make up for the boring Manny Pacquiao bout, many doubted he could pull out such a performance at the age of 40, after being out for two years.
However, he managed to deliver an exciting fight and it seems that McGregor and his team were not up for that challenge.
