Donaire suffers from Roy Jones Jr syndrome. Too damn good for his own good for too damn long, but instead of a weight draining decision being his undoing, he got comfortable and those elite opponents (Darchiniyan, Montiel, Rigo) came too far apart. Dude got so used to dominating C and B level guys with just his talent an athleticism, that he forgot that it takes more than that sometimes to beat elite guys (Rigo) Half assed his training for that fight and the rest is history. He even struggled to stop a guy he KO'ed like 6 -7 years ago in the Vic rematch.
shyt's fukked up in a sense, because more people will remember the Rigo performance/loss rather than all that other raw shyt he was doing like that Dempsey Roll KO he had, or starching Vic and Montiel. Just like you got nikkas out there that think Roy was always some bum after getting stopped by Tarver. It's like the 14 years he was on top don't even matter.
