Yes, I hopped aboard the Cinci train. When the line movement is like this, despite the overwhelming amount of money on the other side, it is telling. Another factor I add in to this is when its against a fan favorite (Yanks, Cubs, Nats, etc...) it's even more telling.
The other night the Colorado/Giants game was exactly the same. When every single factor should lead the line one way and it moves strongly in the other direction, you have to follow that move, particularly when it's a crappy team (as SF and Cinci are).
Someone with more knowledge than me knows something, thus the big swing.
I'm on Cinci. This angle doesn't win every time, but it sure wins most of it.
