I was watching the Showtime 24/7 episodes leading up to this fight. It seems like McGregor is a very bad boxer. He may be a really dangerous killer in his own right but he can't box at all.

Even this 40 year old version of Mayweather is going to pound him into submission. Probably 2 or 3 rounds at most. Unless Mayweather just wants to carry him for more rounds. At least Connor will be well paid for his efforts.
