Not all-out worried, since I think he learned from his mistake the last time he did this. I'm just a little relluctant to believe that Howell can do as good of a job with the defense as Bronco. Bronco deserves a good part of the criticism he's received over the years, but it's hard to criticize his defensive coaching skills. Howell has spent 7 or so years under Bronco, and has been gradually eased into the role, so I think Bronco has finally reached the point where he can trust someone else with the defense. That makes me feel better.
