You are partially right, but mostly wrong. Lines move when too much money comes in for one particular team. The reason the lines move in any direction is to even off the money that has been placed. The bookmakers goal is to have all of the money evenly split between both clubs, then they win by the "vigorish" , the "vig", the percentage the house takes from each bet it charges for making book. The games cannot easily be fixed, especially at the pro level. Sure, occasionally, a ref or a player can be reached by your "mob" but that is a very rare occurance in the NFL. Fixed games do happen in college a little more frequently as it is easier to reach fringe college players that may be needy or be in trouble. Their influence is limited to a play or two and coudl be enough to affect the outcome of a game if the player or ref is in a position at the right time to do something. The edge that certain bookmakers get is from information gathering. A good bookmaker is adept at gaining information about many facets of the game and using that information to set his line and make his decisions as to which way to lay down and influence the flow of capitol to bring about the 50/50 split. To summarize, the game is NOT fixed, no way, it is a hugely popular sport with an enormous honest and above board cash flow. Their is no clear cut real beneficiary of a 'fixed" game that you can come up with. The Patriots lost because in this game they were not able to overcome the adversity that came their way in this game.
