It all depends on the time of movement...was it when the line first came out on Sunday? Or was it just being pounded all the way through the week? Was there an injured player? Did it change right before kickoff? What is the concensus on the game (*********.com has good info on that)
For example, if the consensus is 70% Notre Dame and 30% Air Force, and then right before kickoff the spread goes from A.F. + 10.5 to A.F. + 10...that could indicate smart money really pounding the number, b/c the public was on Notre Dame...
