How about this reason. The books know they have a referee like the dirtbag who got caught last year Donagy in their back pocket so they want lopsided action one way?
Do you guys realize how impossible it is to get 50/50 action on each side? With Parlay's, teasars, reverses, it is impossible to even come close. You have a game like Memphis which started out a pk. They look so dominate last game and UCLA has basically looked like shit. People who have bet it to 2 would bet it to five. They wouldn't switch sides at 2.5, 3, 3.5, or even 4. If you know how to read a line you have to be insane to think these books want 50/50 action on each side. You look at the Sixers game last night they wanted everyone and there mother on Atlanta. Hot Hot Atlanta at home but the line is moving to the Sixers
This is not a case of books wanting equal action on both sides.
