BEST BET: COWBOYS, 26-13 San Francisco (minus 1 1/2) at Los Angeles Rams The 49ers have won seven straight regularseason games against the Rams, who beat San Francisco in the NFC title game last season. The Rams are getting little respect as home underdogs coming off a bye. UPSET SPECIAL: RAMS, 23-20 Tennessee (minus 2 1/2) at Houston Whether it ’ s a banged-up Ryan Tannehill or rookie Malik Willis starting at quarterback for the Titans, expect a heavy dose of Derrick Henry against the Texans.
