JCC superstar was never a legitamate welerweight and was too old to fight the fighters you mentioned. His best days were below that weight, you cannot penalise him for that. It is like criticising RJJ for not fighting Lennox Lewis or Hagler for not fighting Spinks.
JCC hit lightwelter in 1988 and more or less bounced between that and WW for the rest of his career. This was his peak, as he was on the 1b-4-1b lists at that time. Its plausible that he actually peaked earlier but thats getting into fine distinctions. At worst he was beginning the tail end of his peak by 1988.
It is true at 5 71/2 that he was a small welter, like PBF. But so was the aformentioned competition. Using height as a metric, Sweat Pea, McGirt, and Azumah were shorter. Taylor was equal and Randal was an inch and 1/2 taller.
He was not too old to fight these guys. In 1989, JCC was ranked #2 behind Tyson. He was fighting at lightweight-lightWelter-Welter. Pernell and Azumah were also on the 1b-4-1b lists, fighting at lightweight and on the cusp of going to welter. So Chavez had a shot at them at his alledged peak weight.
McGirt was a light-welter in 1988 and made the 1b-4-1b list in 1991 after defeating Brown. Chavez was still undefeated and was ranked #1 after Tyson lost and until his draw with Pernell in 93, after which he got demoted to 2. So McGirt was very doable as well.
Randal marked the end of JCCs peak, but since he was responsible for ending it, he still gets credit for defeating him within his peak. Anything after Randal II, was post-peak Chavez. I would not describe him as shot though.
