I don't know, as I am not a professional sports bettor. Do professional really do this? When I first heard of middling it seemed almost like a parlay to me. Your chance of hitting both sides is slim, but higher reward. I just would think it more profitable to find two games that you really like, however you make that determination that trying to hit this middling crap.

And yes, I am sure redietz will post some essay here or elsewhere about how the blackjack AP knows nothing about sports betting.
