As others have said, Tyson can't pull the trigger anymore, we have witnessed that in the Jake Paul fight. Wherein we really fall for the hype that Mike Tyson can fight and deliver those knockout. While Floyd's style is not to get hit so he will run on this fight for sure. But there are fans that might watch the fight live and so bringing the money that is needed for this fight. And again, money grabbing, easy for both fighters, they are going to cash out their profit here.
For Mayweather it will be an easy money and easy win. Use hit and run tactics, gain points and win. For Tyson it will be hard money, because he would have to exhaust his body again by preparing for the fight and running to catch Floyd. It will be hardest cardio test for Tyson. Training at 60 yo aint no joke. Tyson aint no shaolin monk who has dedicated his entire life to training. He is enjoying his life, and now has to push himself to return to training.
