Heres a comment from a message board , which I agree with:
Mayweather may have won the fight, but the sport of boxing lost it. It was a overhyped media frenzy, played out so only the richest celebrity crowd could see it, and many years after both boxers had led their prime, and in the end it could not deliver. For all the ability of Mayweather as a defensive tactician, maybe even a genius at defensive boxing, that will never be entertaining. When you look at boxing greats, these men went out to fight their opponent, they went for the knock out, not to see if they could dance around for 12 rounds and edge the fight tactically
In 50 years time we will still be talking about Ali V Frazier, the rumble in the Jungle, Hagler V Hearns and a young peak Mike Tyson. Not one Mayweather fight will get a mention as none are memorable. Legacy secure I don't think so. Who pays to watch this. This is not real Boxing.
