98 rating is good and Lions are 5th in PPG. Stafford got short fields this year (not recently though with lack of turnovers and no Agnew) and less drops. No run game though worse than prior years actually.
Let's see if the finger injury affects that in the final 4 games. The ankle injury definitely hurt him with a 3 int game with 12 tipped passes because he couldn't move. And his pass pro wasn't good this year with the injuries to the Lions oline for almost every linemen.
Stafford is an elite QB. Lions need health and the D to step up
2011-2016 Stafford had the worst combo for any QB of drops, rushing support and short fields. This can't be disputed. It's a fact.
2012/2013 major weapon injuries all over the place. Lack of short fields. Weapon caused turnovers. Not much run game in 2012 in yards.
Even the 2013 season was average in rush yards not even a great run game. They were still 22nd in YPC. 2013 had other problems in no short fields, weapon caused turnovers and weapon injuries (lots of Kris Durham)
The 2017 Lions gave him short fields, less drops and healthy weapons (other than Golladay). And despite an ankle injury for a terrible game, Stafford is playing really well with a good rating. Imagine if he had an average run game right now or average pass protection.
