I didn't watch the fight , but I did read up on it.
The way it sounds to me is that this was a bogus win for Bradley. My guess is that it's a setup to get a fighter for Mayweather to beat that has already beat Pac.
This is how Mayweather is going to dodge the Pac fight for good. He'll say, "I beat Bradley and Bradley beat Pac, so I don't need to fight him ever. He's washed up, blah, blah, I'm the best ever, blah blah, blah."
Sounds like a total farce and I hope it doesn't give the sport another black eye (pun intended) just when boxing was starting to get on the upswing.
EDIT: I just read a theory that Top Rank has fixed the fight due to the fact that they see Bradley as "the next big thing" and they want to cash in on 2 fights between him and Pac, (who they consider to be on the decline). If this is true (of course we'll never know) then I will join so many who have decided to say "Scr*w Boxing".
