A season ago, when colleague Ron Jaworski tabbed Detroit Lions' Matthew Stafford as the 13th-best quarterback in the NFL, there were some questions about why he was so low.

Stafford is now lower this season.

Jaworski, who ranked 32 quarterbacks, placed Stafford firmly in the middle at No. 16 -- and it has nothing to do with his talent. Jaworski lauds Stafford's arm, saying his physical skills belong in the top 10. But as many have pointed out -- including in this space -- his decisions and certain throws have always been his problem.

General manager Martin Mayhew fired Jim Schwartz and Scott Linehan in part because of this, replacing them with an offensive-minded staff focused on quarterback development. The Lions' hope is Stafford has a strong enough season where he finally climbs into the top 10 on this list, since it was based on last season's production and throws.

Jaworski also took issue with Stafford's accuracy and reading of coverages, common concerns when it comes to the franchise quarterback in Detroit.

Stafford is not the lowest-rated quarterback in the NFC North. Not even close. To find out who is -- check out his rankings at this link.
