Just watched Nix's hand picked savior of the franchise.  He stated that he had no clue as to what happened to the offensive line play because he had not seen the film.  All he could say was that he had a "sense" that things were not working.  Well coach I've got breaking news for you: digital replay of everything that goes on in the game is instantly available to you should you chose to use it.  It is not really very hard.  You need a bunch of cameras, people to operate them and someone you trust to evaluate what is happening.  Then you might actually be able to adjust while the game is still being played.  Just a thought.
