It is clear you want to start trouble. It is transparent. Most Vegas books opened DAL-3.5. At SouthPoint they took so much money on ARZ+3.5, where it opened universally, that they lowered off DAL-3.5 to DAL-3. Within an hour before kickoff, offshore there was DAL-2.5 (-120) at 5D and Heritage. So yes books need DAL, with all that money on ARZ.(Most money was on ARZ at various lines. Books kept dropping line.)
In terms of the total, it opened at 47.5 and dropped to 46.5. This nominal move suggests money was on the under. So yes books need the over.
What's your motivation? Why would you contribute to this thread with meaningless banter?
Hmmm....
I wish you the desire to want to help others and not only entertain yourself at the expense of others.
