That's a crap analysis you have there. The match is an exhibition match. Do you really think their performance will be at its best? That exhibition match will have a scripted result. Please learn from the past exhibition match of Logan Paul before applying a boxing analysis here.
But if I will counter your statement with a technical analysis of boxing, no way I will consider that age as a disadvantage for Mike. If only they will fight in a professional match, I can challenge you to a bet that Tyson will still dominate the match.
