New to Sports Betting - different spreads

[toby]

Bodog has Dallas +6 (-115) at Minnesota -6 (-105)
Sportsbetting.com has Dallas +4.5 (+175) at Minnesota -4.5 (-210)

How should I interpret/profit from that difference in the point spread?

There is much less opportunity there than you think in terms of pointspread. Football games very rarely land on a 5, so just look at the profit that the bet will offer. Assume you like Minn., if you bet SB.com and win you'll be betting $210 to win $100. At Bodog you'll bet $105 to win $100.

Any decent book on football handicapping will teach you the "magic numbers" along with some of the other dozens of facets to consider. I wish you the best of luck.
