I'm not saying he will physically beat him so bad that he will ruin him like Chavez did to Taylor, but Floyd is about to destroy Ricky Hatton's career for these reasons:

1. He's going to ruin Ricky's perfect record and have naysayers coming out of the woodwork saying Hatton's career was built on beating hasbeens.

2. There's no way after a loss that Hatton can AGAIN decide to run back down to 140 (he'd look like a total coward for doing that twice), so he will now be forced to stay at 147 and fight at a weight where frankly I can't see a single top fighter (Mosley, Cotto, Williams, De la Hoya) who Hatton can beat, thus he'd likely lose his next fight and more naysayers will jump on board saying Floyd ruined him and his confidence.

3. He vehemently dislikes Floyd, just as Hagler vehemently disliked Leonard, and losing to the person you despise the most will eat at you for the rest of your life as we all know it's done to Marvin.
