Go back and read all of the doomsday posts and comments, when Hudson was ruled out...Everyone talking about Donald licking his chops...This was going to be a "get right" game for LA, etc, etc, etc. There was zero evidence that the Oline would perform well, based on the last few weeks. Even if it was just the slightest hamstring issue, the team wasn't going to risk their $250 million investment to further injury. Hindsight being 20/20, it's easy to say he should have played, but again, there was no evidence the Oline would hold up. Also, it's not necessarily about designed runs, but Murray being able to escape the rush up the middle, when the pocket collapses (which everyone expected to happen all game long).
