Any opponent and any venue would be a huge money making fight for Tyson, no matter what you rate his chances of winning (no matter who hes fighting) theres still plenty of people who'd pay to watch it. But whats important is that he doesnt want to fight again and knows that he cant - and as much as ive enjoyed watching him in the past im glad hes called it a day. Fighting on will at best only serve to damage his image and the memory of whats been a great career and at worst really hurt the guy. Hes done.
