Depends on if the rules are slanted to give Paul a chance. And just how much father time has impacted Tyson.
Paul has a 9-1 record in boxing but he hasn't been fighting boxers. MMA fighters may use some boxing but it's not the same thing. I think he fought a couple of mediocre older boxers. And he went the distance against Tommy Fury, but was clearly not in his league.
If you look at Tyson's exhibition against Jones, he is still shockingly fast, and accurate. Look at him in that fight and Paul in his fight with Tommy Fury, and it's no contest. Tyson was fast and aggressive for 8 rounds. Paul's head is locked in position, and when he punches he's throwing his whole body into it. Tyson is too skilled for that to be a winning strategy. Don't think Paul can win even against 2020 Mike Tyson.
But, as a great man once said, the years start coming and they don't stop coming. In your 50s 4 years is gonna make a huge difference. So, maybe Paul has a chance, especially if the rules are adjusted to balance the fight.
