so based on your logic, if the number on atl starts at 100/1 and drops down to 25/1 before week 8 it is because people aren't betting them? not sure if you understand simple economics.
what you said makes no sense and is the opposite of what i said, a movement of 50/1 out to 100/1 before the season is due to ONE reason--lack of bets at the 50's....once the season starts books will adjust prices even before money rolls in, for example you're not going to offer 66/1 if a team is say 4w 1L, when futures prices drop after a weekend's games it has nothing to do with $ they've just taken on that team its about pricing them correctly in your book based on how you assess their chances
