That seems kind of silly to me. Vegas cleaned up in many games. Example. Started BYU -2 at UCF. Betters put so much money on UCF it drove the line to UCF -3. If the book didn't offload the imbalance to another book, Vegas cleaned up on the bettors that moved the line to UCF -3.
Vegas was very happy with the UCF game and you have them crashing? Makes no sense, but carry on.
