Casey I think I know what you're talking about. You're probably using scores and odds or some other sites that briefly gave you Pitt -107 or so. A line that pretty much wasn't released to virtually anyone unless betting overseas.
I bet at William Hill and using Cards -115. Since 9:00 Am it's still not moving toward the Cards side. I think alot of people interpret that differently depending on what their opening line is. Cards are -107 so my line movement has the Cards going from -115 to now Cards @ -107.
If you go to Vegas insider you'll see alot of Sports Books opened the Cards - 130. Still overwhelmingly toward Pitt.
