By the way, there is a lot more to running a sports book than booking bets. There is marketing, avoiding people opening 4 or 5 accounts under different names, customer service, and probably a whole world of things I don't know.
My comments above are only concerning setting the line where you take action.
I do think the really sharp places like Pinnacle, and Olympic can make more money by having sharper lines, but the Don Best "average" line is probably good enough for most as long as you don't take big action.
