This was my first/only thought. Tyson HAD to have agreed not to kill him. Tyson, even at his age now, would have to be on-board in advance with not murdering Paul. It's my understanding that Paul has been hand-fed guys that aren't current, full-time, professional boxers, so he's been able to build up a record.
Even if Tyson agrees to take it easy, Paul needs to be REAL careful not to say/do anything between now and the end of the fight that Tyson could take the wrong way or be insulted by, or inadvertently land too hard of a shot. He's not safe until after the fight is over.
If it's free, I might watch to see what happens. If Netflix tries to charge anything, there's no amount I'd pay to see it.
