Who was/ is/ or has there ever been a rookie fighter(someone over the age of 30) that has been considered a top contender. If so, what kind of record did they have. Just looking for some hope here, I have two of the best trainers(imo) in the buesiness and they say I hit as hard as some of there best, one in paticular is Tyson, so if any of you can help and give this old guy some hope.
