i never even thought about that fight, but Edwin just wasn't consistent enough to beat Alexis, barring a barrage of those bombs, which would be possible. Edwin ended up just being another champion instead of a great. Like Camacho, he started off with a lot of press behind him, being called "the duran of the 80s" which actually fit Chavez much better although Chavez wasn't quite the athlete Duran was, he was a dominant force in those divisions .
So, was Arguello/Rosario ever in the talking stage? Rosario got kayoed by the most forgotten of the top lightweights of that era, Jose Luis Ramirez who fought probably more of the top lightweights in that era than the rest of them and unfairly gets overlooked because he just had no real charisma or interesting style. Gotta be kinda good to hold Whitaker to a draw, and I know people have been saying whitaker was robbed, I watched that a few years ago and I didn't think he was. Americans of that era were ridiculously biased towards american fighters. Whitaker lost at least a portion of that fight because of his showboating, not all judges look at that favorably.
