i think its about time we stop thinking what castillo did in that fight would be a blue print in beating floyd. floyd was younger and now his older and better so looking back at that fight i think makes no improvement in a way to beat floyd. im sure floyd knows what castillo did to give him some trouble and thats why im sure he has worked on it and will make sure he won't be trouble by whatever castillo did again. i think the first fight was close it could of gone either way more so to castillo but the rematch showed floyd was improved and won u.d. All fighters come across atleast one tough fight, that was floyds and lets leave it at that. just me 2 cent
