ANALYSIS: As everyone braces for a shootout, here is a semi-contrarian view. The Bills’ defense remains top-ranked even while displaying some slippage. The Chiefs’ D, though rated low, has made sufficient repairs to raise itself to a decent level. Since these teams combined for 58 points in their Week 5 clash, standout Chiefs DT Chris Jones has returned from injury and ace pass rusher Melvin Ingram was acquired from Pittsburgh. Half of Buffalo’s games this season have gone Under. The Bills tend to prevent big plays, which is Kansas City’s specialty.

ANALYSIS: Points were hard to come by in Saturday’s twinbill, so let’s keep the Under train rolling. On the injury front, 40-year-old Rams OT Andrew Whitworth (knee) will miss the rare game in which he’s not the oldest player. Buccaneers OT Tristian Wirfs and C Ryan Jensen, both Pro Bowlers, are iffy with ailing ankles. NFL elder Tom Brady, 44, was under siege at times last week and could feel the heat from ferocious pass rushers Aaron Donald and Von Miller. He could stick to the most recent game plan with short, time-killing throws. Tampa Bay yielded the fifth-fewest amount of points in the regular season and could bedevil Los Angeles QB Matthew Stafford.

ANALYSIS: Given QB Jimmy Garoppolo’s various ailments and lack of experience playing in an icebox, the 49ers were going to stick to the ground anyway. Now, with temperatures possibly in the single digits and snow in the forecast, San Fran could play this one under a 10-foot-high ceiling, as few times as they will throw. With pass-rusher master Nick Bosa (concussion) cleared, counterpart Aaron Rodgers could look mortal. His completion percentage sinks when under pressure. Forget A-Rod’s 14-6 Over record in the playoffs. This could be a throwback game to the Bart Starr era, when 24 points might assure a win.

ANALYSIS: Incomparable running back Derrick Henry appears poised to return from a length injury layoff, but he is as much a bonus as a necessity for the rolling Titans. They have done A-OK without him. The Bengals’ impressive rush defense will be compromised by injuries to several defensive tackles. They would be right in Henry’s path, so he can make hay even without the usual full load of carries. As complements, receivers A.J. Brown and Julio Jones offer a 1-2 punch -- or more like a 2-3 punch behind Henry. Going with a team off a bye can backfire, but Henry’s likely return clearly benefits Tennessee.

ANALYSIS: Set aside the Raiders’ offensive muscle-flexing last Sunday against the Chargers, and this is a so-so unit, having averaged 14 points in the previous five games. Cincy’s run defense is ranked No. 5 and should keep ailing RB Josh Jacobs grounded. At his best, Bengals QB Joe Burrow is a monster, owing in large part to the magnetic hands of his receivers, but inconsistency and a knack for getting sacked (51 times!) has haunted him. The lethal Vegas pass rush will put Burrow in constant chase mode.
