I think it's because he looked poor at 147 against Collazo. People assume that adding weight generally decreases speed....based on this assumption that Hatton was clearly slower against Collazo.

Problem was he had 7 weeks to train and in that time the extra weight he added wasn't just muscle tissue. He looked a little softer and his pre-fight breakfats was a fried one. That would explain why he looked like shit.

Being a solid 152ish is a lot different from being a botched 152+ which he was for the Collazo fight. Thing is, i think he'll lose this fight anyway and people will point to the weight if he comes in a bit higher
