First line here was GT -3. It's since moved to GT -4 1/2 and -5.
Because the line has moved more in favor of GT tells me that people putting money on the game think differently about things than many on this and other GT boards.
The line could change the other way, but its gone more in GT's favor to this point according to Vegas Insiders.
The oddsmakers don't think anything about our team. They just try to get equal money on both sides.
And the betting public obviously jumped all over Virginia at +6 so that is why the line is tightening.
(Edit) The Stingtalk prediction contest uses the earliest line and it is +6. Not sure about other venues or when they set their lines.)
