That's not really true. Because Vegas would get hammered by sharps if they did that. Which wouldn't lead to even betting.
Vegas usually takes a side nowadays. They don't just try to balance out the bets.
And everyone says this, yet no one finds a way to consistently beat Vegas. If Vegas were not trying to predict point differential, people would beat them over and over again. Nobody does. Vegas spreads are accurate predictors of point differential
This post is nonsense. It's not true that Vegas tries to balance out the bets, because then people would bet, and it wouldn't lead to even betting?
Vegas balancing out the bets is why nobody can beat them consistently. They use high information to set good initial lines, and use wisdom of the crowd and market forces to balance it out if they need any corrections. Your post is basically the opposite of what's really going on: Vegas balances the line by whatever means necessary, which is obviously true, or else they would have gone out of business already.
Vegas are the sharps, as far as any sharps even exist. If they weren't, someone else would be Vegas!
I know people get lost in the tautology of it all but one of the major reasons that "spreads are accurate predictors of point differential" (which I think you would have to provide evidence to show, if it's even true) is that they do try to balance the money. They are high-info to begin with, out-experience everyone else, and then get free information from everyone else who is placing bets with them. The fact that it's closer to even betting is an indicator of how good their line is.
