No easy answer and some good thoughts. I would counter with this - TJ was able to get a team that was totally demoralized to focus and play with intensity when there was nothing left to play for but pride. He put 3 Ws in a row on the table. I'll buy the total rebuild thing, but I cant buy what I saw at the end of the season - BD's team quit at the end of the season. The intangible factor of heart and grit is just so relevant in College Football. A short sleeved TJ in November tells you something and I think it told the players something as well.
The position the coaches found themselves was totally different as well. Coach Weist was basically getting an on-field interview. He was pulling all sorts of rabbits out of his hat. I think Coach Diaco knew he was getting at least two years (most likely three) to turn things around and he took full advantage of that leeway, which worked it's way down to the players. I wish it were handled differently (i.e. more entertaining to the fans), but I'm not sure how. I'm an accountant, not a football coach. I understand most fans' irritation, especially when some pay well into the four digits for multiple season tickets and receive that quality of product that we did. I also understand when Diaco continuously mentioned the general state of the team (Would have liked it if he didn't mention it so often, but such is life. We're not playing Madden here. His system is not plug & play and there is no reset button.
The other thing that gives me a spec of optimism (2 things actually) and why I can't blame Diaco 100% for last year is that he was not the one who fumbled the ball on the first possession for what seemed like 8 games in a row. Diaco did not take one snap or throw a single interception. He did not miss a single tackle or commit a penalty. He gave a lot of players a ton of experience last year and they have had another off season of development. It's a crucial on-field year to be sure.
The other thing was to rearrange his coaching staff because onother 2014 cannot be tolerated. I had to leave the SMU game due to emergency in the 1st quarter, but I saw the parking lots and I saw the stands. Eastern Michigan probably drew more to their final game.
I think last year, Diaco fought the fights that he could win (Perfect APR, weed out the WKG, install a work ethic, etc.). This year he needs to fight the fights worth fighting. UCF's leading returning receiver had 12 catches last year. They also lost their top 4 tacklers. That combined with what Diaco has presumably seen of his team, what if he actually wins the second Civil Conflict (BTW, I think Snow Bird Bowl would be a better title for it)? That is when a rivalry starts to take shape.
