In my opinion, Erik Seidel is probably the most underrated superstar of the game. While there are others that get more fanfare (Phil Ivey, Daniel Negreanu, Scott Seiver, Phil Galfond, Isaac Haxton, Patrik Antonius, Phil Hellmuth, and many others), there's no doubting Seidel's ability at the tables. He is so even keeled and just picks his spots so well.
I'm hoping that he wins a bracelet or two this year.
