I fort I started late!
There is still hope
Funny you bring this up, I find alot of times alot of posters seem to think they have started to late due to being past the age of 18, and dont even bother to try. As I have proved with my list, this is not the case.
Lots of fighters have started in there 20's and went on to have huge success in the prize ring.
Kermit Cintron
Paulie Malignaggi(real close to 18, won golden gloves 1 year after)
Nate Campbell
Glen Johnson
Antonio Tarver
Many much more...There was a list published not so long ago around here.
