There are a lot of misconceptions, especially on this forum, with regard to the merits of closing line value. I think its important that people get away from comparing their numbers with the Pinnacle closer because obviously Pinnacle's prices have a built in house edge at the off. A few years ago Betfair introduced the BSP (Betfair SP). This is the most accurate predictor of a horses true chance of winning a race and it has been proved over a mass amount of data that a horse with a BSP o for example 2.0 will win 50% of the time.
I have no doubt that this will also apply to US sports on Matchbook due to the high level of liquidity on there. Therefore if the Yankees as 2.5 on the moneyline you can expect them to win the game 40% of the time. So rather than wasting time worrying about sharp books and Pinnacle just note the prices of games on matchbook at the off and if you're beating that price on a consistent basis you can confident;y expect to win in the long run.
There were other rubbish theories thrown out on the forum about point spreads not predicting the actual winning margins of matches which is completely ridiculous. Regardless of what point spread Matchbook puts up on its market, the money will tell you the perceived percentage chance of ta team is to cover that number and has nothing to do with the likely winning margin. Again I would believe this to be almost perfectly efficient by the game off.
In a perfect world someone would would have the ability to get the raw data on Matchbook closers and this could be proved right or wrong but I'd be amazed if it wasn't highly efficient on predicting sporting outcomes.
So if you want to bet better you should be cognisant of what price your moneyline or point spread ticket is at the off on Matchbook.
