Sometimes you basically depend on the age bracket and how long it participants in a fight will determine it's wining, Anderson Silva (47 years old) and it may be that it has not lost it weight of fighting, but people in another means of understanding will directly like Anderson Silva because of it's age and the high odds also. Why people will not to give Jake paul 27 years old as amateur or newbies in fighting, and they will not like to choose.
If we based on their age than for sure make Paul has a advantage it because as we all know 20 years of behind is a good enough and a young fighter fight his older opponent which is veteran enough and had many experience in the world of fight so Silva has advantage in terms of fighting skills, experience and technique but in terms of age then like what I said make Paul had advantage.
