NAME some popular and unknown boxers (from past to present) whose resumes look great on paper until you look into their competition. I'll start with a modern guy, Gilberto Ramirez.
You talking about their numbers? Juan Coggi has a nice looking record: 75 wins with 44 KOs, only 5 defeats (none by KO) and 2 draws. He was WBA 140 champ in two reigns between 1987 and 1994, made a combined 10 defenses and picked up the title for a third time in 1996... ...but he never dared risk his title against the no. 1 fighter in the division for most of the time he was competing there - Julio Cesar Chavez. Moreover, he was a hideously protected 'champion' who benefited from appalling officiating on more than one occasion. His infamous 1993 defense against Eder Gonzalez was hands-down the most blatantly corrupt bit of officiating I've ever seen (and makes a mockery of his unblemished KO record) and his 1996 title 'win' over the oft-shafted Frankie Randall was controversial too after Coggi was cut and he got the technical decision. He lost the first and third fight to Randall which was more reflective.
Julio Cesar Chavez....the ironic thing is that his record is the reason most of his haters don’t like him ( I’m a huge fan btw )
There was a point in time where San Francisco middleweight Pat Lawler had back-to-back wins over Wilfred Benitez and Roberto Duran in 1990/91.
Marty Jakubowski took his first loss in November 1992 to Julio Cesar Chavez to bring his record to 37-1. Little more than two and a half years later he got his first title try against Miguel Angel Gonzalez - he was 90-1 on fight night, packing 53 wins in in those 30 months, mostly in 6 and 8 rounders against lowly opposition. He took his second loss that night.
I think of Jakubowski as the poor man's Sean O'Grady (74-2) in that at least O'Grady managed to successfully make the step up at championship level.
What's popping up for me are guys who started off strong against unknowns, but then didn't do nearly was well when stepping up. Alex Stewart, before Holyfield I. Mac Foster, before Quarry.
He was actually solid in the late 80s and early 90s though. Patricio Olivia, Harold brazier and Jose Luis Ramirez (although on the decline) were very good scalps. Yes, the Edel Gonzales incident was a farce. As he aged he was protected more and more by the WBA but so was JC Chavez by the WBC. Frankie Randall was victmized twice once by the WBC and once by the WBA in bogus calls against these favorite sons.
