Who was the biggest amateur star that accomplished the least as a Pro

Ricardo Williams
Francisco Bojado

John Scully?
Sechew Powell?

I'd say the biggest one of recent times is Jesus Gonzalez.

 

I think in Sanders' case he deserves a pass in this topic. He died during the first year of his professional career and I've read that there was something wrong with him physically going into that fight and his tragic end may not have been entirely due to his opponent in that fight.

I guess if we are strictly going by the topic, then yes, Sanders did not accomplish much as a pro,. But there is a big difference between Sanders' career and the career of Harrrison, who is in the 8th year of his boxing career and is barely a blip on the heavyweight radar.
