NFL: Week 3

San Francisco -2 1/2 Kansas City - On the one hand, a winning record for the Chiefs means Arrowhead will be loud. On the other hand, the 49ers are a good squad on the brink of 0-3 which will mean a spirited effort. The Chiefs are still searching for some points from their offense, which they're likely to need today. Vegas still slightly overvalues Arrowhead, you have to go all the way back to 2006 to find a season where they were didn't have a losing record there ATS.
