You are certainly entitled to your opinion Winbet, but you are focused on something completely different IMO. Everyone who has ever bet college sports knows the opportunity that exists in the early season if you are on top of things. The vast majority of the money bet on college sports, especially football, is not very informed. It is far more informed than it used to be thanks to the internet, but still not where it should be. You can literally count on getting value in the first few games betting on teams that should turn things around and against teams that should fall apart, if you have done your homework. The betting line will adjust somewhat, maybe half-way, but not the full way to where the line should be. If Auburn was a 105 power rating last year and in your assesment an 85 this year, you probably will find the books treat them as a 90-95 team. If this a team like USC, the public perception of a great program and how they have fared in the last few years means the book has to make the number even higher, say 95-100. This has nothing to do with public money and such, its the bookmaker making sure he doesn't get sided like crazy. He can't make them an 85 this year as a perceptive person would because he would take on too many bets on one side and the book isn't about to do that. He doesn't mind taking a decision where he thinks the line may be in his favor, but most books aren't crazy enough to write 99% of all action on one side and hope his pre-season analysis was right.
I will set aside a list of teams I want to back and fade, then set up a strategy very early. Of course I will look at the lines, but in almost every single instance of doing this for over 10 years, I have been wrong about the numbers that actually get posted about 5% of the time. The books still have limits to how much they will adjust a view of a team and it has nothing to do with proper analysis. It has to do with the fact that they take bets from the "public" and if the public isn't adjusting their numbers properly, why shouldn't there be value for us to exploit? No it doesn't win every bet, but for the first few weeks of college football I have picked at a 60% clip over the years, with very little work needed after doing some research in July and early August.
