Since you are being positive and encouraging good discussion on the sight I will participate too. I have never thought it matters much what happens to the line after I bet if the line moves and gets worse because that means I got the best odds. And there are certainly times the public and the pros are on the same side. Todd Furman has been mentioned here a few times he is one of the sharpest guys out there, and he mentioned a recent NFL game where the pros and joes were on the same side.
For the real biggest bettors like the Billy Waters of the world they have to wait until late because the limits are higher and they need to bet as much as they can!
