Jon Thaxton didn't drop him. Vince Phillip is a big puncher. Collazo isn't exactly feather fisted. Hatton always struggled at 147. Again, 147. Plus Mayweather's power is under-rated, and they were crisp, sharp punches he didn't see. Far enough, but I think his punch resistance was gone by this time. How do you explain the hell he took off Kostya Tszyu? An ATG 140 puncher & fighter. How do you explain a few of the shots he took off of Juan Urango, another monster puncher. You don't get to be a world-class fighter with a style like his and a defence that bad without having a good chin.
I didn't say he doesn't have a good chin, i am saying his punch resistance isn't gone, i'm getting sick of everyone trying to downplay pacs victory with hatton is shot crap he has never had an iron chin he was so successful early because his competition sucked, once he stepped up he started getting rocked/wobbled//ko'd.
That's some funny ****! Did Collazo look all that bigger on fight night? Nope. Truth is that it wasn't the 7lbs, it was that Ricky just wasn't "that" good. He was a good fighter, and beat some quality guys, but he was never EVER elite.
