I don't think the casual fans opinion should be discounted, but take everything with a grain of salt and know where it's coming from.
Concrete example, if you will: my wife is from the Philippines. After the fight many of her friends/family had a pic up on FB that was going around. It was of Floyd leaning back with his arms crossed, as he is prone to doing, and Manny coming forward. Caption read ''picture says a thousand words'', implying of course that Floyd is a coward and Manny really won.
As I explained to my wife, not a boxing fan herself, the picture makes a silly and somewhat self defeating argument. Floyd is leaning back like that because he's a brilliant defensive boxer, and he can. You can't look at a round, much less a picture, and say ''x or y won that fight'', that's not how boxing works. But I understand they are disappointed, Manny is like a national hero, and a lot of these people don't really follow boxing, or understand it, outside of him.
So yeah, everything in it's proper contest. Many here understand boxing better than the casual fan. Doesn't make one or the other's opinion invalid, but it's a question often of who's saying what, and why.
I mean according to brut, we are damn close to needing to start a church for Mayweather. That doesn't make his opinion invalid, but you remember who you're talking to, you know?
