I can only speak on my own record when I get on or off a play because of the line and it is not good. In 2004-5, I played nothing but consensus plays that I disagreed with before I knew they were consensus plays. This however led to me being unable to form an opinion without knowing what the line was first. Call me stupid I guess. Anyway......
I can remember one guy who made 4 and 5 team parlays off reverse line movement in college football each saturday morning and he hit most of them that I saw. I considered that significant because most of us can't even hit one of those season. He was hitting more than one a weekend. Anyway....
I'm just getting sick of reading about this line and that line being "fishy". Or reading about what "vegas" wants on a particular game. The reason why they make money(presumably they are profitable) is because we as a betting public have no clue about how they accomplish that goal.
Maybe lines aren't fishy. Maybe books have loss leaders the same way that retail stores have loss leaders.
