I think
Irishsecra1 got it right in the way I feel. I was all in and the early results seemed on a path to match the excitement. I won't give the credit for 2018 to Shafer. I liked his style of D and I wanted him to work out, but I agree he needed to go. He had some cringe moments in the press, and his teams seemed to be getting smaller (he couldn't beat the B1G schools in his mid-west/Ohio recruiting base).
I loved Dino for the locker room excitement and the "neener neener we've got a dome" stuff. Good swagger. Even him saying "go to Franklin and PSU" exhibited a confidence in what he was doing. That went away. Football alum complaints got louder. The offense got worse (Sterlin Gilbert was a disaster). He ignored his own back yard and recruited Hawaii and California (a GRob mistake that many of us recognized fairly early). He started blaming players and using excuses for poor performance. At the end, he had all but quit and it was jarring how fast it was happening. I believe that (the speed with which it looked like we were headed back to the basement) was/is the cause for a lot of the perception of animosity toward him. The pain of returning to one win seasons was too much and many here have lashed out.
