The referee did the right thing. McGregor was in too deep by the 10th round. He was a punching-bag at that point - just standing there with his arms down by his sides. He was no longer defending himself. Letting it ride out would only have put him at risk of more brain-damage. And, I don't think the points were that close - Mayweather had a definite edge, and that edge was only going to get bigger if the fight went on.

Don't get me wrong - I honestly would love to have seen McGregor win this fight, and wipe that stupid, smug smile off of Mayweathers' face, for once. It was a good fight. The outcome was actually predictable - because it went into the late rounds. McGregor would have had to catch him in the first few rounds with a real haymaker to win - or Floyd would have had to not show up, show his age - and that just didn't happen tonight. No way was McGregor ever going to be able to seriously school somebody as good as Mayweather in the boxing ring, when it comes to a true boxing match. In the MMA ring, it would have been an absolute slaughter, with opposite results - but this isn't the MMA - it's boxing. Honestly, I thought McGregor made a good showing - proved he is one of the top fighters in the world. He was just out of his element.
