For me, it was 3 fighters. 1. SUGAR RAY LEONARD No dis-respect to Hector Camacho, But it was TOO DAMN painful to watch "Sugar" get DESTROYED Camacho. After the UD lost to Norris, I thought he was done...and when I heard he was fighting Camacho after a 6 YEAR LAYOFF.....I KNEW WHAT WAS COMING!!! SAD!!! 2. ARTURO GATTI I had no problems with Gatti losing to Baldomir and Mayweather...Baldomir was just too strong and Floyd was WAY TOO FAST...But watching Gatti get DESTROYED by Alfonso Gomez was a F**KING TRAGEDY. About 3 months after that fight...I saw Alfonso at The Sin City Boxing Gym here in Vegas...I WANTED TO KICK HIS ASS!!!! PUNK!!! 3. MIKE TYSON With Tyson, I don't know if it was Hanging on way past his prime as it was more of just the TRAGIC DOWN-FALL of his career. but watching Tyson get TKO'd by SOFT-ASS Kevin McBride was a DAMN SHAME. Peter McNeeley could beat McBride. Oh well...those are the fighters on my list. There are a few others that were hard to watch get destroyed later (past their primes) Donald Curry and Julian Jackson were painful to watchg also.
