DC didnt start mma until he was 31 years old. After a 5 year career, a 36 year old DC lost to a juiced up prime 27 year old Jon Jones who had been fighting for 7 years already. DC lost by one round. DC was at the end of his prime when he started mma. I submit that a 7 year 27 year old DC smokes a non juiced up version of the Jones he lost to.
