Age isnt always a factor, there are far too many examples in sports that proves that. In boxing, ill use Hopkins. Just because hes older doesnt mean he isnt better. Linford Christie at 35 / 36 was blowing away the worlds best sprinters, Paolo Maldini approaching 40 was still one of the best defenders in the world at football.
All im saying is Tyson's prime lasted 2-3 years in his early 20's before he went into an evident decline, and yes he is the greatest "what if" in boxing.
As i said, its just my opinion. Doesnt mean you have to agree or disagree and it doesnt mean its right or wrong.
