Who is the most talented boxer to never achieve anything and fade away into obscurity

[Kirkland Laing]

Scratch the last one, there is hope for him. I called him a top prospect in 2012 and he only fought once in 2013. But per boxrec he has been active in 2014 Jose Benavidez.

4 years: only 21 fights welter being brought along too slow IMO- unless he is injruy prone-set to face Muarico Herrera.

In addition to the hand problems he also looks to have a glass jaw. He got caught by a non-puncher in one of his recent fights and was out on his feet. How he survived the round I don't know. He was still wobbled at the end of the fight. His jab is a thing of beauty though.

A Latin Hearns?
I remember Gil Clancey commentating on Barkley-Hearns "The one thing about a Hearns fight, you know Somebody is gonna get knocked out."

Hearns had that right hand though. Hearns would be a massive PPV fighter these days just with that KO power. Imagine how much Mayweather-Hearns would make.

Benavidez has the jab, some power (not Hearns-like) and some silky skills but has the hands and the chin slowing his ascent. If he wants to get to world level he's going to have to be able to take punches.
