Fighters you ABSOLUTELY thought would have turned out better.

What fighters at some point in their career did you feel would turn out to be better, more popular, more successful or greater than they are? Who disappointed you when you had the upmost confidence in them? I'll start off with Berto. You go straight to the 2:40 mark of Round 7 in his fight against Angel Rodriguez and it just became more fuel to my thought that he was the next big thing. That his blend of speed, power and athleticism would propel him. However the Collazo fight took a lot of steam off of his impressive showings and there was no rematch to right a close victory.
