In reality, the players(particularly the square side) are busy betting the board with props, qtrs, halves, teasers, and parlays, losing back what they may win on the favs covering some sides. It is easy to say the favs are covering so the books must be losing, but the vast majority of players have to have a bet going and they are not content with one or 2 solid plays. If they do get up, the addiction takes over and they start wagering the board looking to satisy it. I am not sold on the books doing bad stuff. With so much action and other sports going I would hope the books are doing ok. Maybe I'm wrong. Action is a necessity for many and in the addiction, players who thrive on action will not likely come out ahead. Fact is the majority of bettors lose, Period!
