Just my opinion, but I think that's way overblown. I try to concentrate on picking the side that has the best chance to cover. If that's the public side, so be it. Contrary to popular belief the public gets games right too...
I started using the fade public train of thought this season and what it does is give you just one more good parameter to base your pick on. It shouldnt be the only reason you take a side because its a game and the public does win sometimes. The books however are in business because the public loses the majority of the time. Another useful tool to go along with that system is perception. What I mean by that is when a team plays a great game and plays well above what people expected the book knows that team may get overvalued by the public the next week and set a line that induces a bet on that team.
