Manfredo is actually a decent fighter. He's improved since the contender under new trainer Freddie Roach (Manny Pacquiao's trainer) and has grown into 168 very nicely. One of his losses coming off the contender to Sergio Mora was a robbery but since then has beaten 2 decent top 25 guys, Pemberton & Spina, both by very impressive 3rd round stoppage.
I don't disagree. He's a decent fighter, and possibly eventually he'll be able to fight at a world class level. However, he's not ready yet, and Calzaghe isn't just a fighter at the World class level - he has few peers.
The only reason Calzaghe is fighting Manfredo is because of the extra exposure he can get on HBO and the Bika fight was dirty.
That, and the money. Calzaghe's earnt the right to fight who he wants - and hopefully the exposure will make sure he gets the biggest fights - and the money that goes with them.
Frank Warren said after Bika there would be a "mega fight" well he lied.
Warren says that about every fight - it's his job! That fight was just a mess really.
Hopefully he sticks to his word this time and a fight with middleweight champ Taylor is next up, then fight Mikkel Kessler at Super middle to be the first fighter in history to unify all 4 major titles at 168. (tho Joe just ditched the IBF)
They're the fights we all want to see. Again, I think Calzaghe will win them - but the hardest fight might be outside the ring and ensuring they actually happen.
