Watch Gatti's wins over Tracy Patterson. Rios could never box like that against an opponent of that caliber and even keep it close, let alone win. Gatti abandoned his formidable skills on favor of a more exciting style and adulation of the fans. Rios is just a limited, straight ahead banger with a good chin. They r both similar in that they have a never say for attitude, but Gatti, in my opinion, was a couple levels up from Rios and more versatile.
