some people would say being 'sharp' would be to take -6 and +7 if the vig attached was less than 20 cent combined.
What I said was if you like a team they open +4.5, and you bet them +5 but they might get to +5.5 somewhere, and they may close 5. You got 'better' than the opener but didnt 'beat' the closer, and you didnt even get the best number. But if the team wins SU what does it matter?
Like I said I went back and ran the numbers where lines moved. in a vast majority of cases you were going to win or lose no matter what.
But people think beating a closer means they were on a side that more 'smart' people bet which caused the line to move, and since they beat the steam (the old version of the same concept) they were better off. hich isnt the case.
I bet Tampa Bay Bucs +8 this past week, they got to 9.5 in a few places, not exactly sure what they closed at, but they lost by 6, so regardless they won at every number, so getting a number that 'beat' the closer may technically be true it really didnt matter since no number on them lost. Similar to the Patriots, that line was all over the place, but the Pats covered every single one of them. So it didnt matter if you beat or didnt beat the closer.
But by the wording of your statement I can tell you fall right into the trap and the dumb line of thinking., no offense. But sports betting IS random, it doesnt have anything to do with how the lines move, or that a linemoves increases your chances of winning or losing depending on what side of the line move youre on.
The only thing that increases your chances of being a 'successful' long term gambler is having enough winners to overcome the vig you pay on them. Its really that simple. Problem is most people could win if they didnt pay any vig. So the rest is immaterial.
