NFL quarterback rankings, Week 6: Andrew Luck is back

Dave Krieg Division
25. Marcus Mariota (LW: 23)
At what point do we start labeling Mariota as a bust? The Titans need far more production from the fourth-year veteran. Tennessee scored measly 12 points in a laughable loss to the Bills, and Mariota went for 129 yards and an interception. It’s terrible football.
24. Ryan Tannehill (LW: 21)
Tannehill played so well the first three weeks of the season, but things have begun to come undone in a major way. After throwing for 100 yards and getting benched for Brock Osweiler (the game was out of hand), Tannehill threw two more interceptions against the Bengals, including one of the most bizarre throws you will ever see.
23. Mitchell Trubisky (LW: 25)
After throwing six touchdowns against the Buccaneers, Trubisky and his suddenly-golden right arm got the week off. This weekend? Trubisky and the Bears take on the Dolphins down in Miami. If he sparkles again, Chicago could finally be onto something.
22. Dak Prescott (LW: 22)
Prescott didn’t play great against the Texans, and really he’s been bad for more than a year. So why isn’t he lower? Have you seen Jason Garrett? The Cowboys have no chance of winning games with him in charge of the offense. It’s impossibly brutal.
21. Eli Manning (LW: 24)
Manning finally plays a quality game against the Panthers, and what happens? New York loses at the gun on a 63-yard field goal in a season where most kickers struggle to knock home an extra point in warmups. Manning ranks 15th in yardage and completes 71.7 percent of his throws, but six touchdowns in five games isn’t doing it.
