How is this anywhere the same?

In a scam, you don't have any way of making any future correct predictions--it's just random. This analyst has a reasoned system that can be tested against past players and against future prospects. Sure, there's going to be someone out there that picks Jeremy Lin. But the trick is, can you correctly identify players who are already known to be good based on their college stats, make the right call on Jeremy Lin, and go forward and continue to make good calls on draft prospects?

I'm not saying this sabermetrician generally makes good calls; I haven't looked. But dismissing his call as the result of a series of Bernoulli trials is completely missing the point.
