Sam Farmer’s Week 13 NFL picks

Lines according to Glantz-Culver (O/U = over/under). Last week’s record: 10-6; season 99-77 (.563). Using point spreads with the scores Farmer predicted, the handicapped record would have been 9-7; season 87-89 (.494).

Denver at Kansas City
Records: 3-8; 7-4.
When: Sunday, 10 a.m.
TV: none. DirecTV: 704.
Line: Chiefs by 8. O/U: 48.
The Chiefs are at home, have more incentive to win, and -- the way Matt Cassel is playing -- should be able to avenge their earlier loss to the Broncos. Chiefs 28, Broncos 20

Cleveland at Miami
Records: 4-7; 6-5.
When: Sunday, 10 a.m.
TV: none. DirecTV: 705.
Line: Dolphins by 4. O/U: 43.
The Browns should be able to run the ball, but turnover-prone Jake Delhomme will have problems against the desperate Dolphins. Dolphins 41, Browns 21

Buffalo at Minnesota
Records: 2-9; 4-7.
When: Sunday, 10 a.m.
TV: none. DirecTV: 706.
Line: Vikings by 5. O/U: 44.
This won’t be a layup for the Vikings, who have yet to assemble consecutive wins and might not have Adrian Peterson. Still, they should hold on at home. Vikings 24, Bills 21

Jacksonville at Tennessee
Records: 6-5; 5-6.
When: Sunday, 10 a.m.
TV: none. DirecTV: 707.
Line: Off board. O/U: Off board.
If he can play, Kerry Collins (strained calf) will be even less mobile than usual. Maurice Jones-Drew should have a big day for the Jaguars. Jaguars 21, Titans 17

Washington at N.Y. Giants
Records: 5-6; 7-4.
When: Sunday, 10 a.m.
TV: Channel 11. DirecTV: 708.
Line: Giants by 7. O/U: 43.
Donovan McNabb has had a lot of good games against the Giants during his career, but he’s a different player with a different supporting cast now. Giants 24, Redskins 13

Chicago at Detroit
Records: 8-3; 2-9
When: Sunday, 10 a.m.
TV: none. DirecTV: 709
Line: Bears by 4. O/U: 44.
This one isn’t likely to come down to a do-or-die pass like the last meeting. Chicago is coming off a convincing victory against a top-notch opponent. Bears 24, Lions 17

San Francisco at Green Bay
Records: 4-7; 7-4.
When: Sunday, 10 a.m.
TV: none. DirecTV: 710.
Line: Packers by 9. O/U: 41.
The Packers are at home and are great at pressuring the passer. Aaron Rodgers will make the 49ers regret (again) passing on him in the draft. Packers 27, 49ers 14

New Orleans at Cincinnati
Records: 8-3; 2-9.
When: Sunday, 10 a.m.
TV: none. DirecTV: 711.
Line: Saints by 6. O/U: 46.

Records: 5-6; 6-5.
When: Sunday, 1 p.m.
TV: Channel 2. DirecTV: 712.

Atlanta at Tampa Bay
Records: 9-2; 7-4.
When: Sunday, 1:15 p.m.
TV: none. DirecTV: 713.
Line: Falcons by 3. O/U: 44.
The Falcons are playing great football, whether they’re at home or on the road. The Bucs are 0-4 against teams with winning records. Falcons 23, Buccaneers 17

St. Louis at Arizona
Records: 5-6; 3-8.
When: Sunday, 1:15 p.m.
TV: none. DirecTV: 714.
Line: Rams by 3. O/U: 43.
A divisional win would do wonders for the Rams, who are vastly improved on defense and have a fast-rising star in Sam Bradford. Rams 23, Cardinals 20

Dallas at Indianapolis
Records: 3-8; 6-5.
When: Sunday, 1:15 p.m.
TV: Channel 11. DirecTV: 715.
Line: Colts by 5. O/U: 47.
Peyton Manning was pounded by the Chargers and his line has plenty of holes to patch. It’s hard to see him dropping a second in a row at home, though. Colts 28, Cowboys 24

Carolina at Seattle
Records: 1-10; 5-6.
When: Sunday, 1:15 p.m.
TV: none. DirecTV: 716.
Line: Seahawks by 6. O/U: 40.

When: Sunday, 5:15 p.m.

Records: 9-2; 9-2.
When: Monday, 5:30 p.m.
TV: ESPN
Line: Patriots by 3. O/U: 46.
The Jets have won eight in a row on the road, and Mark Sanchez has been outstanding vs. division foes. But the Patriots just don’t lose these at home. Patriots 27, Jets 24
