It looks like we've run the marathon here and are still on the start line. We'll just have to agree to disagree. I place the majority of blame on the Titans D lack of success on poor execution, missed assignments and the inability to win enough one-on-one matchups on the players. You think scheme and coaching deserve the bulk of the blame though you continuously point out how the top players in this defense are inconsistent in your article series (which I am enjoying, btw). I'm guessing the truth will come out in time. With half the season left, we will get to see for ourselves how the defense responds. And if the current level of play is the result, then I'm sure we'll see a new DC and scheme next season and will get to see its impact. But one last question: If the players were not missing assignments, blowing coverage, whiffing tackles, etc. how much better do you feel another DC would make this current defense?
