I think Murray just closes his eyes and runs wild. He has no feel for the game/run. He would make a great pinball machine(copyrighted here first) guys.
I am not convinced Emmitt would do that much better here with all conditions staying the same.
There was a play yesterday where Murray took the had off, and I shouted for joy as I saw a huge whole open to his right. Easily could have picked up 15-20 yards. Instead he ran right at a linebacker and picked up 3. Whoo fucking hoo
