Keith Thurman talks about the boos he got, said Screw those fans.

[Wuckoo]

Why so many people are mad at him cause he said that he KO Bundu inside 4 rounds and he called out Floyd etc...
You really buy anything what a professional fighter says before his fight to promote himelf? It's just PR, sel promotion, don't feel yourself cheated. Almost every fighter promises KO's, lol...
I mean I can't say anything more common in this sport than X says that he will KO Y.

Haha, it's true. Roach has said countless ***** to promote fights and hardly any of it has ever been true.

Thurman having to have excuses made for him already, and all he fought was Bundu. Not good. This dude is getting less legit as he progresses. Screw the fans, sure, but screw your fights also. Haymon is going to sideline Thurman again for 2015. It must be an interesting position to be playing second fiddle to your peers, while getting booed at the same time. Respek.

There are some terrible audiences in the US. Thurman fought well, probably should have tried harder to hurt and stop Bundu at some point but perhaps he was taking no chances with his previous injury or maybe him and his trainer were happy to get the rounds in. I understand the disappointment that he didn't do more but the booing was ridiculous.

How it's always been. But I also think a bunch of posters/fans/media are drunk etc on fight night and just say a bunch of really dumb nonsense.

There is a lot of truth here.

Drinking at an event does make people hate quicker.

In general, anyway.
