Chris Sacca seems like a good person and straight-shooter, but I am having a hard time reading any more reasoning out of this than "I think he's hard working and he's really good at Wii Tennis". It could have been any game, and it's not like he's secretly best-in-the-world at all games. He got lucky (when it comes to the game chosen by his opponent) in a casual encounter playing video games at a cabin. Surely we are approaching the horizon where completely random statistical noise is being swapped out for insight?
