Hitman, exactly. People think a 15 cent move awya from them gives them an edge, well it does if they had the original number because then they couold bet both sides and not lose.
But the only way to know if you have any kind of edge at all is to have a reference point, period. And even then, if you are betting one way, then you still have a watered down edge. I bet anyone would have said that Balt PLUS 2.5 was a great EDGE, well guess what, it lost. Actually in reality Balt PLUS 7 wasn't even that good, but that kind of cover may come under the ehading of having the righ tside and losing, as Balt had a gimmick play for a long TD, then an over turned call (correctly so BTW) and the very next play was a punt return for a TD.
But to try and say that you can look at a game and say you have an edge by a certain amount is craziness. People now think that Minn has more value because theline has gone up on them. Maybe so, but if they lose what does the value really do for you? Getting the extra penny or nickle or dime only matters when you WIN, not just because you got it.
But as my WHOLE statement said, math is only relevant when you can use correlatuions to figure out a true perceived value, win or lose. But that also entails having the ability to buy the other side back for a profit as well.
All you jokers that make your own line or own number go back and look at all the games you have done. I would bet my bankroll that you were more or less right btween 48-52% of the time either way, to me that is a losing propsition, and basically a coin flips chance. So where does math really matter in that sense?
