The team that has the minus sign, which is the favorite, has points deducted from its final score, while the dog, with the plus sign, has points added. The favorite must beat the spread, which means they have to win by more than the negative number to pay off. The underdog pays off in two instances—if they win outright or if they lose by less than the spread.

BetOnline excels when it comes to betting on any sport, visit them today and give them a chance to prove it...it will not cost a cent!
The key to successful betting lies in quality and not quantity. Your overall chances of winning are much greater if you pick your spots carefully, and only bet when you find real value. There isn't a huge number of NFL games each week, but there's enough that it's simply not realistic to think you can handicap them all. And if you're also betting on college games then this is even more of an issue.
That was all before Charles McNeil, a math teacher from Chicago, invented the concept of the point spread. An avid gambler, McNeil created what he called “wholesaling odds” and started his own bookmaking operation in the 1940s. He started out offering this new style of betting on football, but his business model grew to include basketball. McNeil changed the way sports betting was done, and his legacy lives on today in what we now call the point spread.
