Haters still salty about the lack of the camp, even though the fight was done in under 2 rounds so it's not like you're even legitimately complaining like say if Mendes was finished in the 5th, despite the fact that one of the reasons why Mendes' ground game failed was because Conor started beating the shit out of him from the bottom. Which made Mendes not even want to be there, even though that's where he was supposed to be safe. Being prepared for 5 rounds isn't going to suddenly change that Conor surprised Mendes with his aggressive ground game when Chad thought Conor wouldn't be able to do anything.
There's nothing from what actually happened that would suddenly turn the fight around if Chad was ready for 5 rounds. Conor was too much on the feet, and causing too much damage on the ground. This was exacerbated by Chad's gas tank, but was not a symptom of it. It was Conor being too much and Chad not having an answer that worked.
Camp or 2 week camp, you're still going to end up with the same deer in the headlights right before Conor KO'd him because Chad simply didn't have an answer for Conor and didn't know what to do. It was be outstruck or be elbowed to the dome.
The real difference was Conor didn't hesitate like Chad started to.
