This is so true, and sometimes it starts with something little. As a little interesting aside, I remember a European soccer player a few years back kept having lower back trouble and hamstring injuries. Eventually they figured out it was because one of his teeth was a millimeter too long or something like that. It meant that when in a resting state his jaw was locked more tightly than it should, leading to the muscles on the left side of his neck being too tight. This in turn meant his back muscles were too tight and then his hip and so on all the way down to the hamstring. It all went away when they shaved the excess length off the tooth.
Back on topic it feels like Saffold's played his last snap for the Rams. The guy is just always hurt. You can't rely on him and pay him $6m because you can be almost certain that he's going to go down hurt again and this will disrupt the line, and stop you bringing in a replacement who can stay healthy even if he's not as talented as Rodger because you hang on to the hope that he'll be ok. That's why even a $3 saving in the cap hit might be worth it - just to mentally say "Ok we're moving on" and get a new starting quality guy in.
