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

The injury bug!!

Does it not feel like the Saints have a sytemic problem in that regard ? Is it just the turf at home ? Poor conditioning? Poor technique?

Just to play "hypothetically", if the Saints had 50% less "lost time from the starters", they most likely would be in the Wild Card/NFC South champ race even now.
It doesn't. It had more to do w/ the voodo of this years energy. Look no further than how the Pelicans suffered the same fate.
