Injuries are one thing, but these coordinators have no creativity.

It's both, no takent and KK isn't good. The offense was terrible before the bottom fell out and the starters on offense were still playing. I'm sorry but McCoy being injured should not have been such a huge factor. He is at most a 2 point differential player.
they scored 90+ points the two games before all the injuries hit. that doesn't seem too terrible to me. once McCoy went down, all went downhill. the cap is so bad, the team can't afford decent backups and has to rely on below average, vet minimum talent and this is what it looks like.
