There is no money at those odds. In 10 years I've never seen anyone make profit at those odds. If someone posts such picks it's a big red flag they're clueless about value. Even a 66% win rate loses 1 cent per bet. Win rates are for wannabe pros and touts, the only thing that matters is the bottom line.
There is however one sport where those odds can be profitable and that's tennis. But in team based sports, forget it. We've all seen those NBA, NFL and college sports MLs around here go horribly. If someone posts a at -350, take the dog spread to hit at least 55%.
