I amazed at how much the average bettor's opinions change after one game. Last week NOBODY wanted to bet on Atlanta and they win big and now it seems everyone is jumping on Atlanta +7.5 this week. Most people were on Jacksonville last weekend now most are against them. Nobody wanted Green Bay last week and everyone was on Detroit and now everyone is on Green Bay.
This is why the average bettor loses. He just remembers the last game. Are the Falcons suddenly good because they beat a weak team with an awful defense?
One thing that always amazes me about bettors is that they always pick the game after an embarrassing loss to bet against a team. That is the worst time to go against a team, especially in the NFL. These are professionals and they tend to play their best right after playing their worst.
