What went wrong with "Kid Chocolate" Peter Quillin?

[PRchamp]

4 fights in 4 years. He was a part time fighter who overachieve and his raw talent got him this far.

To me he always looked scared getting hit plus when he got destroyed by Jacobs it scarred him

he was using PEDS to cut down in weight and fight in a lower weight class. dude was always a stiff.
