They both have already won. I hear Paul is getting 40 million and Tyson is getting 20 million. That's just the purse, who knows what other opportunities were gained from the exposure.
Win, lose, or draw, the storylines write themselves. If Tyson loses, it was because he's 58 or he threw the fight. If Tyson wins, it's because he is Mike Tyson.
It's a train wreck, but "we" the public, fall for it every time.
