Honestly, I'm not wumming, and I'm always open to reasonable debate. But Ricky hatton is without a doubt the most overrated of the bunch when it comes to hyped up U.K. Fighters.
His technique was below average and his jab (as mocked by mayweather many times on the 24/7 build up show) was disgustingly bad for a professional boxer.
Hatton benefited more from media hype than anyone I can remember. The man he beat for the WBU light welterweight belt was Tony Pep, a man who wouldn't make a top 5000 list of boxing champions at any weight class. As the new champion, he was extremely well matched for his next half a dozen fights and knocked people out/forced stoppages with ease but the calibre of opponent was laughable. He kept winning, and when the opponents got a little better in quality he started winning decisions (one of them pretty suspect IIRC) then he got a couple of extremely easy fights that he knew he could force a stoppage. With that, they built up the kosta fight and you'd have been forgiven for thinking tszyu was the second coming of sugar ray Robinson. The fact is he was past it, and should have retired after he beat zab judah. Anyone who watched kosta two fights before hatton knew that he was gone as far as being competitive against a younger hungrier fighter went.
Hattons skills were exposed so badly against mayweather that I'd refer to it as the fight to watch if you want to understand the term "taking someone to school". Pacquiao knocked him out with absolute ease.
Anyone who holds world titles, it's hard to refer to them as a mediocre boxer, but in hattons case it's absolutely true. A warrior, an excellent heart and amazing fan a base but as a pure boxer he was just really really bad.
