Yeah, especially with the totals. It always amazes me how consistently on they are.
Rarely do you catch em' napping.
However, once you realize that they are this good, it does make you more careful and therefore a better sports bettor.
I've spent today live betting these playoff games. Sometimes you can catch a good opportunity with game flow or momentum going one way... etc... Took San Antonio moneyline 1H when they were trailing in the first quarter. Panned out well.
I don't know how rich the average online sports book owner is, but Vegas? It's a small operation for most casinos. I think I read that the average sports book at a Vegas casino, accounts for like 5% of their income. However, I'm sure the head guys rake in a pretty penny, and I'm sure they pay their line setters very well.
