In the video the majority are math nerds. Probably crunching odds, whilst still reading the players. Seasoned players though so see your point. What's the top prize in the biggie?What's most interesting to me is how so little player interaction is shown and how much more the commenting is about what's going on that you don't see. It's more about the game instead of TV showmanship.
There's a bunch of WSOP tournament games already finished up and plenty of video available. Still more to follow, including the Big one in July.
