Quote: Were players like Daniel Negreanua and Barry Greenstien at one time broke, and how many other "world class" players have gone broke at one point or another?
OP, you're going to get flamed for this and I can't say it's not deserved. Seriously, have you been living in a cave for the past five years? Do you know anything about poker?
The answer to your question is probably "almost all of them." Don't forget a large number of professional poker players are degenerate gamblers. Not all of them, but a lot. Of course they go broke from time to time.
Furthermore, who gives a flying [censored] if Brad Booth is broke today? Even if he is, within a month, he'll probably have more money than I'll ever see. I really don't think we have to worry about Negreanu, Booth, etc. ending up out on the streets.
