Vegas Books certainly know what they’re doing, but this week’s point-spread of Baltimore opened at -4 went -3.5 now -3 in some spots!!!again and again shows a certain lack of respect for the 49ers,whose only loss came in week 2--an overtime loss to Dallas.The line basically says that the Ravens are a half-point better than the Niners, with the customary 3-point allowance for home-field advantage. With a 9-0-1 record ATS,one would think the lines would be inducing bettors to take the opposite side.This week,however, it’s somewhat surprising that one can still find good value on the 49ers?????? The 49ers (9-1) can clinch the NFC West with a victory against the Ravens (7-3) and a loss by Seattle against Washington on Sunday.Their lone loss came against Dallas in overtime back in Week 2, as they have reeled off eight straight wins both straight-up and against the spread.San Francisco topped Arizona 23-7 last week, and each of the team’s last six games during the winning streak has been decided by six points or more. 49ers quarterback Alex Smith has played well for the most part this year,but he will face a tough Baltimore defense whether linebacker Ray Lewis plays or not.Gore,who has been limited in practice due to a nagging right knee injury, ran for 88 yards on 24 carries Sunday.He bounced back after being held to zero yards on six carries Nov.13 against the New York Giants after averaging 126.8 yards in five games prior to that performance.he Well Ladies & Gents anyone trying to time it right for a 49ers non-cover can attest to the futility in picking against San Fran this season. Time and again,they have delivered.Their in a bad spot though this week.Having to travel and then play on a short week is a major disadvantage even for the best of teams.There's a reason that the spread hasn't moved lower than a field goal while the world is hammering the Niners plus the points.Because Baltimore is going to win and cover and the bookies know it.Don't get suckered into this trap line with the Vegas books?Bet the Ravens minus.-3 points and keep in under your hat.
