Despite the star power of this final table, the fact that only 15 people are watching this event play out is testament to the fact that watching no-limit deuce-to-seven is very, very dull. There's not as much excitement or speculation as is possible with flop and draw games for the simple reason that spectators don't know any of the cards that any of the player are relying upon. It's also a slow game -- dealing out five cards to every player takes time.
The three remaining players at the table probably don't care. They're all focused on the task at hand -- taking down the bracelet in this prestigious tournament.
