LC, Frank would disagree with you. Given his *many* conversations with other coaches this offseason, his desire to shake things up and the slogan "restore the roar" (amongst several other examples)...it seems quite clear that Frank was unhappy with the momentum of the program.
Thank god Frank realized that things had gotten stale instead of blaming the fans, graduated players or departed coaches. We needed a shake-up and I'm optimistic that Frank and staff have delivered it.
Frank's desire to shake things up really happened a year earlier, between 2013 and 2014. That's when we saw Frank really unhappy, and we saw major changes, things like new methods for electing Captains to improve leadership, and the Navy Seal Training, to improve unity.
I felt like the changes this year were more fine-tuning the changes he had made before, things like new stretching methods, or changes in how much and when the team had contact in Fall Camp. Putting it another way, I felt like the changes between 2013 and 2014 were designed to totally change the direction, and the changes between 2014-15 were designed to keep the team healthy, and thus to keep the new uptrend from getting sidetracked by injuries.
I believe that the direction changed last year, and I still mark the Buffalo game last year as the reversal point.
