Firstly, Conor won't fight Chandler, but if he did..
Not even a McGregor hater, but the partying lifestyle makes the mind week after a while.
Performing at the elite level means depriving yourself in a basement, in the trenches, keeping the mind clean / focused.
If McGregor gets grinded for 5 minutes, he's going to give up and drown in there. The extra weight will only hurt Mcgregor, Chandler is going to be quicker on his feet and won't stop the pace. Without Usada, Chandler is also going to be even meaner this time around.
If McGregor is serious about fighting, he needs a real camp, and to give up drinking for at least a year.
