The running preseason betting theory is if you know little to nothing about an event other than there are two outcomes then from your perspective the probability of each outcome is 50/50. If you flip a coin and know the force used to flip, distance, angle, etc. you can get predict a probability greater than 1/2.

Betting the underdog in preseason ( > +110 ) is up ~10% on 133 bets so far.
