Any so-called handicapper who thinks an MLB team should be bet because they've "won 90 out of 155 when the Total is 8 to 8.5" (and usually the pick is heavily favored anyway!), or that an NBA team is worthy of a wager because they're "64-47 when coming off an Under the Total" is operated by a complete fucking moron.
I agree.
Here is an segment using the type of analysis you are talking about from Oskeim yesterday which resulted in a GOM LOSER.
I always get a particular chuckle whe he uses the word "investing" rather than the rightful one of "gambling" when referring to the outcome of a sporting event.
From a technical standpoint, Chicago is a profitable 26-4 (+21.7 units) versus National League starting pitchers with an ERA between 4.70 and 5.20 and 22-11 (+13.1 units) after scoring nine or more runs in its previous game, whereas the Diamondbacks are a money-burning 1-8 (-7.2 units) versus left-handed starters, 7-17 (-11.1 units) following a loss and 5-14 (-11.1 units) in games with a total between 7 and 8.5 runs. Take Chicago and invest with confidence.
