Theory question: How many lines are "off"?

[smbruin22]

i think you're basically asking "what % of lines are completely wrong?"....

but then i'm not sure if florida is 10 point favorite, but loses by 10, if that line was "wrong" or simply variance/circumstance/injury etc.....

here's what i'd like to know: how often do you see lines that you think are "easy money"??....two that come to mind are the UNDER on that early FSU/Miami and the point spread when miami and nebraska played for national title.
