This is very likely to happen. Mike is a veteran yet old and anyone such as Manny who is 46 years old, is likely not fit to fight regardless of how long he is trained for the fight. The body is just not meant for it anymore when you reach a certain age.
Although Pac was able to strike, he wasn't as efficient as the way he was. He was just lucky that the Japanese didn't have good footwork to overturn a fight but Jake is great in boxing apart from that he is young, and he was trained for years.
Both are great and legends in their own right, but age has caught up with them. So we shouldn't be too hyped that Mike Tyson would be able to beat the young and very active Jake Paul, as we might only be disappointed in the end. Boxing nowadays is not just about talent but also proper training and technique, and it's very evident that Jake Paul has acquired the skills and great technique in boxing. So it's hard to believe that he'll lose against an old Tyson.
