The books don't really want balanced action 5team. You can't make money like that. let's face it, other than the sharps or wiseguys, who's going to take the other side when there's lopsided betting on a team? Think about it! If you like the Steelers and you wait until gameday to make you bet, but in the meanwhile the line has crept up from 4 to 6. Now while you're hemming and hawing about laying the 6 while standing in line at the book, a ton of money comes in on the Steelers and the line moves to 7. What are you going to do? Since you already have your heart on betting the Steelers, and you feel they're going to kill Seattle, you either are going to suck it up and lay the 7, or get out of line and hope the line drops back to 6. Unless your a sharp, you're not going to change your allegiance in mid stream and bet the Seahawks are you? Of course not! If it were the regular season with other games to bet, you might say the heck with it and bet another team. But since it's the only game in town, and you MUST bet it, you'll probably wind up taking a teaser for 6 or 7 points so you can get the pointspread down to where it's reasonable. The only problem is, that now you have to take the total which you may not have a feeling for at all.
Even if the books are on the wrong side, it just might be that the total is a blowout one way or the other which kills all the parlays and teasers, and this helps them balance their books with these type bets. Throw in the hundreds of proposition bets where they have a greater edge with the higher juice, and that even adds more to the bottom line. It also helps them that they don't allow parlays on prop bets so their exposure is limited.
So basically what it comes down to is that there really isn't any "evening out" as far as books are concerned. That's probably one of the biggest lies ever. The average "Joe" is either going to bet the team he likes at whatever price, take a teaser to reduce the line, or just say the heck with it and bet the total if it hasn't changed that much. He's just not going to turn around and bet the "wrong" side because the line has moved. If anything, he just might believe that one side that's moving is a steam play and jump all over it no matter what the price. That may not be logical, but when the "herd" instinct takes over there's no telling what can happen!
