If Chavez met Nelson at Featherweight I'd love Nelson's chances. At Jr.lightweight, a competitive Chavez win, at lightweight Chavez wins convincingly.
Chavez at his best was the bigger of the two and beat a lot of contenders at the higher weight. I have to favor him for these reasons
I love Nelson as brave, strong as hell, gifted, talented, an iron chin an brutal puncher but the prime Chavez , the man who ruined Rosario was simply even better ... the prime Chavez from 130 to 135 was an all time , all time great ...
