Amateurs just aren't the pros and I agree that it's not the end of the world, but there's been cases of top flight amateurs getting in too deep off the bat and have never been able to get their careers on track. Even Rigondeaux found 23 rounds, had 6 professional training camps, and still struggled in his first big fight against Cordoba.
The amateur system is just so different that you need to through the pro ranks before trying to make it happen. He could fight quality guys without taking monstrous steps up. Fight a solid guy that hasn't been stopped in a 8-10 rounder so you can see what it feels like, fight one of these "good record" guys that are built to get washed later on by prospects. I'm sure I'm ranting now, but I've never liked this regardless of how great of an amateur the guy is.
