What about the (other) elephant in the room: Injuries

Looking at the injuries of what the Lions have endured this season and with their current record is pretty good. They're also in one of the toughest divisions in the NFL. Sure, the Saints had some injuries to key players but to be this bad at the end of the season is just making excuses. Our players are just not that good.
Our BACKUP players are not that good. Most of our starters are quite serviceable.

Going back to 2010, we had PT, Chris Ivory, and Reggie Bush.
Now we have Alvin Kamara and everybody else who pretty much stink.
