Well, keep in mind this is the top 'legends' list, not just top players. After all, would you put Binion on a top 10 players list? Personally though, given the nature of this list I would've put Harrington on there, winning a Main Event and then FTing the 2 that really put it in the limelight is really an achievement.
My list would go something like this:
1. Doyle
2. Slim
3. Binion
4. Ungar
5. Moss
6. Pearson
7. Hellmuth
8. Harrington
9. Annie Duke <- Gotta give a little love to the ladies, plus she totally punked Hellmuth
10. Chan/Men The Master/Ivey
Honorable Mention to Raymer. Beat a big field, then went deep against a HUGE field, and with nothing but class.
