ESPN Chad Millman interviews Bob Scucci, top sportsbook guy for Boyd gaming. Scucci says he tries to set odds that will result in him having a position on some games. He sets lines to take advantage of people betting on public teams. He would be OK with 75% square money on one side and 25% sharp money the on the other side.
I tend to believe him since I can't think of any advantage to him saying this if it's not true.
Millman podcasts are nearly all interesting.
