Well, the whole idea that the 'skill' demonstrated in Corrales-Castillo was far greater than Ward-Gatti is ridiculous. Neither fight was an example of boxing prowess on display. They were blood and guts slugfest and there wasn't anyone jumping up and down about the "skill" being used. That's horseshit. Combined, Castillo and Corrales are the better fighters in my opinion, but it is not on a completely different level than Gatti and Ward. Hell, Ward is a stretch naturally, but Gatti is every bit as accomplished as Corrales was.
Try telling these guys that. The only true skills demonstrated that night was the ability to take a beating by both men. they put their heads down and slugged.
While i agree that Silva would not be competitive in boxing, being KOed by a 19-2 guy in your first boxing match has happened to FAR better guys before and can't be really used as an argument.
