20. Case Keenum (LW: 20)

Keenum did a nice job against the Steelers, putting the Broncos back into playoff contention with an upset 24-21 win at Mile High. There’s nothing special about a season line that reads 13 touchdowns and 10 interceptions, but he’s improving steadily.

19. Marcus Mariota (LW: 23)

Here’s a line you might never see again. Mariota completed 22-of-23 passes on Monday night for 303 yards and two touchdowns. Somehow, the Titans only score 17 points in a blowout defeat. Tough to blame Mariota, who was under pressure all night and nearly pitched a perfect game.

18. Mitchell Trubisky (LW: 18)

Trubisky missed the Thanksgiving win for Chicago, sitting out with a sore shoulder while Chase Daniel captained a victory. The question here is whether it’s concerning that the Bears looked like the same team with a career backup while Trubisky looked on. We’ll see if Trubisky gets back on the field this Sunday against the Giants.

17. Matthew Stafford (LW: 14)

Stafford has to take the blame for that atrocity of an effort against Chicago on Thanksgiving. The Lions held the Bears to just 16 points on Turkey Day, only to watch Stafford throw two brutal interceptions including the eventual game-winning pick-six and a game-clinching flub in the end zone.
