NFL Week 13 odds: Indianapolis at Detroit

The Colts look to continue their improbable playoff push Sunday and officially end the Lions’ chances of returning to the postseason. The Colts will go for their sixth victory in seven games while the Lions try to avoid a fourth straight loss.

The Colts are 6-1 in games decided by seven points or fewer and their average margin of victory (6.1) is the lowest of the 10 NFL teams with at least seven victories. Indianapolis’ minus-14 turnover margin is the league’s third-worst.

Colts rookie quarterback Andrew Luck was sacked four times in Sunday’s win over Buffalo, which bumps his season total to 26. At this pace, he would finish with 38 sacks taken.

The Colts expect to get cornerback Vontae Davis back from a knee sprain that has kept him out of the lineup for four games. Since he’s been gone, the other starting cornerback, Jerraud Powers, suffered a season-ending toe injury against Miami on Nov. 4.

The Lions (4-7) haven’t played well in close games — all their losses are by 10 points or fewer — and they’re on the verge of losing four straight for the first time since a five-game skid Nov. 7-Dec. 5, 2010.

Quarterback Matthew Stafford has the NFL’s top pass offense at 312.5 yards per game, but perennial Pro Bowl wide receiver Calvin Johnson commands the most attention. His 1,257 receiving yards lead the league. About a quarter of Stafford’s 296 completions have gone to Johnson, a speedy 6-foot-5 target who can do it all. But Johnson’s touchdown count is down. After 16 scores last year, he has four this season. Stafford has completed 60 percent of his passes for 3,429 yards, with 14 TDs and 10 interceptions.

The Lions have been inconsistent defending the run (123 yards per game) and were gashed for 205 yards (7.3 yards per attempt) in their Thanksgiving Day loss to Houston. The Colts don’t field a ball carrier like Houston’s Arian Foster, and making Indianapolis one-dimensional could be achieved out of Detroit’s base 4-3 front. The Colts’ offensive line deficiencies could be exposed this week as the Lions’ defensive line matches up well in the trenches.
