I think RS and others do a stellar job of telling people what NOT to do gambling-wise, which is of much more practical use than spilling the beans on a play that, if you spill the beans on, is gone.

More money will be saved learning what NOT to do than will be made from transient plays.

Rob's value is in what he tells people NOT to do.

As far as sports betting goes, sports statistics have been data-mined 24/7 for more than the last decade by people with very sophisticated programs. There are no real secrets. If you win, it's because you know your stuff, not because there is some hidden thumbnail angle or statistic that other people could learn.
