I think I get what you are saying but have no numbers for you. I have noticed when the underdog covers the first meeting in college they cover the second. Maybe it is my imagination. Like today. Pitt covered against syracuse getting 10 at home when two weeks before they only lost by 14 on the road and covered. Now they get ten at home and proceed to cover Seems to happen that way. SF covered against Gonzaga in the first and got even more points the second meeting and covered again. Would be interesting if someone wants to spend the hours to do research. Maybe it only happens with big lines I don't know If I got time....maybe.......
