Gamboa or Rigondeaux. The Cubans bring the flair, excitement, and most importantly, the solid fundamental skill but they all have Glass Jaws.
Junior Jones. His legs were tooth picks, but he was so talented and had he been blessed with "iron chin" punch resistance he would be an ATG fighter. Vivian Harris is another choice of mine. Great skills, cant take a punch.
i don't think he was glass jawed. his fights with barrera prove otherwise. he only got stopped when he was shopworn.
James Kirkland. An exciting style, intriguing personality, the makings of the next big thing in boxing. But that chin is gonna hurt him.
