Definitely past his prime but he's still formidable considering his win over Katsidis and the level of resistance he displayed against Marquez. The proposed Valero fight would have been ideal imo.
I'm not sure how I feel about this honestly. I don't like the decline in punch resistance for Casa. That said if he IS going up in weight, I think he has a VERY decent shot at beating Devon Alexander.
I used to think the same way, then I stumbled upon an old interview he did from 2001. The guy is just absolutely incoherent no matter the time period.
