Don't think of it so much like "Steelers or Seahawks" risk 110 to win 100. Think of it like a horse race. 5/2 on the favorite, then 4/1, then 7/1, etc. etc. The total of it all may be somthing like a 7% make-up for the bookie. Who pays the vig?? The losers of course. A football game is like a 2 horse race with each horse equally likely to win.
