Stafford is unsure how Detroit's offense will change under new offensive coordinator Jim Bob Cooter, the Detroit Free Press reports.

Cooter worked as an assistant under Caldwell in Indianapolis and also spent a year with Peyton Manning in Denver before joing Detroit last year as quarterbacks coach, so his background isn't tied to his predecessor's offense. Still, to Stafford's point, it is hard to envision the Lions' offense changing too radically in a few short days, but there may be more tweaks in store after the Week 9 bye. In the Lions' lone win this season, Stafford completed eight passes of 20 yards or more, over a third of his season total. If Cooter is able to return the cannon-armed Stafford into more of a vertical attack, it could spark a return to the kind of production he put up in past seasons.
