I just re-read my posts on the first page of this topic from June 15th and now it almost sounds like I knew what I was talking about:
"Most Mayweather fights I would say go the distance as Floyd will play it safe to secure the victory. But I have a feeling all the little shots McGregor takes are going to affect his stamina and he'll be an easy target in the late rounds for a TKO."
"I hesitate to chalk it up to conditioning, because McGregor will be well-conditioned. But you're absolutely right that there is a difference in the type of stamina he will need. Not only will he be going for more rounds, but he'll still be taking shots here and there for the first five rounds. McGregor has never taken shots for five straight rounds. That will be different for him, mentally and physically. Even blows that don't knock you out or wind you, still affect your stamina. That's why I think he'll be a sitting duck for some bigger, cleaner shots in the later rounds like you suggest."
