NFL Week 8 Bet On It: San Francisco (-7) at Arizona

The 49ers have been an against-the-spread juggernaut under Jim Harbaugh, but the public has finally caught on, as evidenced by 4-3 record ATS in 2012. The best bet in this game, meanwhile, may be under 37.5. Each team has consistently been under, especially in the rough and tumble NFC West.
