Boxing is foreign to the way McGregor fights so anything he does in that ring is going to be alien I guess.

Who has Floyd legitimately knocked out the size of McGregor? Back in '05 and 140 pounds was the last time Floyd was stopping people.

Unless McGregor is exhausted late in the fight (a very real possibility) I see it going the distance. Floyd has fought safety first since moving to welter and I don't see that changing now.
