ORCHARD PARK, N.Y. — Buffalo Bills general manager Buddy Nix would rather wait a week before providing a detailed assessment on what went wrong this season, and how he intends to fix it.

When it comes to sharing a general thought, Nix says there was "no excuse" for the team's seven-game skid.

After a surprising 5-2 start, the Bills (6-10) closed with a familiar thud by losing eight of nine to miss the playoffs for a 12th straight year.

If that's not enough cause for concern, leading receiver Stevie Johnson further clouded his future in Buffalo.

Eligible to become a free agent, Johnson was benched Sunday following his latest questionable touchdown celebration during a 49-21 loss at New England. Johnson did not make himself available to reporters Monday, when players cleaned out their lockers.
