Dave Birkett sounds the way the man covering the Detroit Lions should: dour. During the conversation he discusses:

• Defensive lack of identity in the post-Suh era.
• How age is starting to catch up with the Lions roster at various positions, including wide receiver and linebacker.
• Why Matthew Stafford is losing confidence of Lions fans and quite possibly ownership.
• Calvin Johnson no longer being Calvin Johnson.
• A possible bright side for the remainder of the 2015 season. (Hint: it starts with Lions winning Sunday.)
