I've worked in the business
I've lived and worked in the business here in Las Vegas and
off-shore for 15 years now and the "men" setting the #'s could
care less about public opinion, outside of one game maybe
(Superbowl), due to the volume of wagering on that event being
enormous. The opinions they care about are the opinions of the
big, heavy, bettors that they are currently booking that they
can hopfully make them go one direction or another that favors
their operation.
Example if your biggest players are Dog players for the most part,
the man would fade towards keeping the numbers lower, in favor
of the favorites bettors, but not fading it too much to lose their
(customers) business. Or if the book is getting alot of play on the
favorites, just not moving the #'s knowing that eventually it will
be even out with a few big plays late with big dog action from
their (bookie) bigger players that generally play dogs. It's just
a matter of knowing your bigger players and if you respect their
plays and respect their money management skills. Bookies I have
worked for we're very keen on picking up on wether they should
respect someone or not!
