My betting site has the Steelers at -4 right now as most do. I believe the line started out at -3.5 .... I would like to bet on the Steelers and regret not taking the 3.5 (not that its a huge difference, but you never know).... My question is this: If I wait a little longer, do I have any chance of the line shrinking, or is it most likely to grow because of the huge Steeler fan base nation wide?
