What changes do the Lions need to make after their bye week?

The Detroit Lions bye week is upon us after five weeks of up-and-down football. The team enters the break on a high after trouncing the Arizona Cardinals 45-21 on Sunday, but there is still room for improvement across the roster and coaching staff. The bye week is an opportunity to get healthy and get reinforcements, and the Lions will surely benefit from the return of Brian Branch and Cade Mays to the lineup, among others. However, the bye is also a time to reflect on what has and has not worked early in the season.
